Abstract.  Geostationary Operational Environmental Satellite (GOES)-14 imager was operated by National Oceanic and Atmospheric Administration (NOAA) in an experimental rapid scan 1-min mode that emulates the high-temporal resolution sampling of the Advanced Baseline Imager (ABI) on the next generation GOES-R series. Imagery with a refresh rate of 1 min of many phenomena were acquired, including clouds, convection, fires, smoke, and hurricanes, including 6 days of Hurricane Sandy through landfall. NOAA had never before operated a GOES in a nearly continuous 1-min mode for such an extended period of time, thereby making these unique datasets to explore the future capabilities possible with GOES-R. The next generation GOES-R imager will be able to routinely take mesoscale (1000km×1000km) images every 30 s (or two separate locations every minute). These images can be acquired even while scanning continental United States and full disk images. These high time-resolution images from the GOES-14 imager are being used to prepare for the GOES-R era and its advanced imager. This includes both the imagery and quantitative derived products such as cloud-top cooling. Several animations are included to showcase the rapid change of the many phenomena observed during super rapid scan operations for GOES-R (SRSOR).

The Geostationary Operational Environmental Satellite (GOES)-14 was operated by the National Oceanic and Atmospheric Administration (NOAA) in an experimental super rapid scan 1-min mode to emulate the high-temporal resolution sampling of the future Advanced Baseline Imager (ABI) on the next generation GOES-R series. This test took place from August 16, 2012, to October 31, 2012, with a gap during parts of September and October. Imagery was acquired of many phenomena including severe convection, fires, smoke, and hurricanes. During typical GOES operation, images are collected every 15 or 30 min. The 1-min imagery allows users to visualize phenomena while they are happening, as opposed to what has already happened.

Previously, 1-min GOES images have been shown to be useful during postlaunch science tests (PLT) and other nonoperational periods to monitor fog, clouds, rapidly developing convection, and a distinct “aircraft dissipation trail” (otherwise known as “distrails” or “hole punch clouds”).1 Often the PLT super rapid scan data represent just a few days of data.2,3 In the fall of 2006, 1-min data were collected during the GOES-10 traverse of the continental United States (CONUS) as the satellite was positioned to a longitude of 60 deg West, from 135 West. During this time, “a forecaster at the Nashville, Tennessee, National Weather Service (NWS) Weather Forecast Office (WFO) had access (via the Internet) to the experimental GOES-10 1-min visible satellite animation” and used the information to correctly reduce the size of a watch box,1 showing the potential value of the rapid refresh mode in warning decision making.

The 2012 GOES-14 1-min data are a unique resource since the 2006 GOES-10 data, though extensive, were collected while GOES-10 was changing its subpoint and after GOES-10 had been operational for approximately 8 years. The GOES-10 image quality was affected by an increased satellite inclination. These high time resolution image sequences bring the satellite image temporal frequency on par with that from other datasets, such as from radar, lightning mapping, and other remotely sensed and in situ measurements.

Demonstrations in the GOES-R Proving Ground with the NWS, including the National Hurricane Center (NHC), Storm Prediction Center (SPC), and the Ocean Prediction Center (OPC) have shown forecasters the benefit of these fine time resolutions in rapidly changing environments.4 In the Proving Ground, products are demonstrated with, and receive feedback from, forecasters using proxy and simulated datasets. Some of the key products that are very useful for high impact weather forecasts and warnings include cloud and moisture imagery, hurricane intensity, convective initiation, overshooting convective cloud top (OT) detection, and lightning detection.

A deficiency in these product demonstrations is the inability to more fully demonstrate the added utility of the GOES-R imagery products at the higher 30 s to 1 min mesoscale refresh rate that will be routinely possible with the ABI. This is especially applicable when dealing with rapidly changing phenomena. In the demonstrations, NWS forecasters evaluate the planned and future capabilities of GOES-R in the context of their current and planned suite of observing systems and numerical weather prediction models. For example, at the Hazardous Weather Testbed in Norman, OK, the forecasters have access to simulated cloud and moisture imagery products, convective initiation, overshooting tops, cloud-top cooling rate, and 1-min Oklahoma total lightning mapping array (LMA) density maps while at the same time having access to dual polarization radar and National Weather Radar Testbed Multifunction Phased Array Radar rapid refresh 1-min volume scans.5 Therefore, unique datasets can be collected in central Oklahoma consisting of the GOES-14 super rapid scan operations for GOES-R (SRSOR) proxy data for the GOES-R ABI and the Oklahoma LMA proxy data for the GOES-R Geostationary Lightning Mapper (GLM) concurrently with the radars forecasters rely on for nowcasting and warning of high impact and severe weather.6 While not covered in this article, GOES-14 also acquired SRSOR images during the summer of 2013 on select dates in June and August.

Characteristics of GOES Imagers

The two Earth viewing sensors on the current GOES series are the imager and the sounder.7 The nominal field of view is approximately 1 km at nadir for the imager visible band, although the detectors are oversampled in the east-west direction.7 The technical aspects can be found in the GOES N/O/P data book.8 Many operational products from these sensors are derived, such as the cloud products (height, properties, etc.), atmospheric motion, biomass burning, smoke, and surface properties (e.g., land surface temperature). Current plans call for GOES-14 to become an operational satellite in 2015. The GOES-14 imager has five spectral bands (Fig. 1); see Fig. 6.1 of 3 for a plot of the visible spectral response function. The current GOES imager routine operational schedule scans a full disk (FD) image every 3 h as well as a CONUS or “extended Northern Hemisphere” sector as often as every 15 min. In contrast, for one scan mode, the ABI on the GOES-R series will provide FD images every 15 min, plus CONUS images every 5 min and mesoscale images every half minute (or two locations of approximately 1000km×1000km every minute).9 Hence, the special 1-min imagery of GOES-14 foreshadows what will be routinely available from the ABI on the next generation geostationary satellite series (GOES-R), scheduled to be launch ready in 2016, and operational in early 2017. GOES-S, the second in the series, is currently slated to launch in 2017 and become operational in 2020. A second possible scan mode is that the ABI only scan FD images, but do so every 5 min. The ABI will be better than the current imager in a number of significant ways. For example, faster coverage rate, improved spatial resolution (by a factor of four), on-orbit calibration of all bands, improved bit depth, more spectral bands (by over a factor of three), and improved Image Navigation and Registration.9 This means the imagery from the ABI will not have the gaps that the current SRSOR has when a FD is scanned. Nominally, the period for a given low Earth orbiting satellite is approximately 90 min, although there are multiple polar-orbiters. There is little overlap between orbits over the mid-latitudes and tropics so these observations primarily provide snapshots of the atmospheric state and cannot capture the rapid evolution of phenomena as is routinely captured by satellites in a geostationary orbit.

Super Rapid Scan Operations for GOES-R

The GOES-R imager will be able to routinely take mesoscale images every 30 s (or swapping between observations of two widely separated phenomena every minute—e.g., an Atlantic hurricane and a Great Plains supercell tornadic storm). These images from the ABI can be acquired even while concurrently scanning larger areas, such as the continental United States and the FD. In general, the SRSOR schedule from GOES-14 consisted of 26 images every 30 min, with the exception of the 30-min gap every 3 h during FD images and during stray light (SL) testing (04:45 to 09:14 UTC). There was no SL outage during the late October collection of Hurricane Sandy (known as “Super Storm Sandy” in some media outlets) data, since the special scans needed for the SL correction algorithm had already been collected. The SRSOR allows for more rapid imaging than the standard Rapid Scan Operations (RSO) or even the SRSO. While the SRSOR scans an area nominally each minute, the RSO is only as fine as 5 min (and at times only 10 or 30 min). The SRSO has 1-min imagery periods that are broken up by other longer scans of approximately 5, 9, and 30 min. All these schedules require a FD imaged every 3 h, which leaves the 30-min gaps. The 1-min sectors from the current GOES imagers are approximately 1100km×1900km over the mid-CONUS (Fig. 2). More information on these operational scans can be found at NOAA’s Office for Satellite and Product Operations (OSPO) web page: http://www.ospo.noaa.gov/Operations/GOES/schedules.html, while http://www.ospo.noaa.gov/Operations/GOES/14/srsor.html lists the scans associated with the SRSOR 2012 experiment. For most of the experiment, GOES-14 was positioned at a longitude of 105 deg west, although the images of Hurricane Sandy were scanned from approximately 90 deg west. The location of the scanned area was determined the preceding afternoon, based on a number of factors such as the SPC outlooks. These coordinates were then communicated with the satellite operators. In general, the same schedule and center point were operated for 24 h.

The schedule that was run during the SRSOR test varied due to a number of factors, including the potential weather, other satellite schedules, and out-of-storage planned testing (Table 1). The “default” schedules allowed for testing of changes to the routine schedules. The Continuous East Full Disk is a schedule that takes successive FDs, nominally every 30 min. More information, such as the daily schedule, coverage area, and satellite animations, on the SRSOR in 2012 can be found at the University of Wisconsin-Madison’s Cooperative Institute for Meteorological Satellite Studies (CIMSS) web page: http://cimss.ssec.wisc.edu/goes/srsor/GOES-14_SRSOR.html. Scientists at the Cooperative Institute for Research in the Atmosphere collected the SRSOR data in the real time, converted it to the proper format, and sent it to the SPC in Norman, Oklahoma, where it was displayed in their National Advanced Weather Information Processing System. This supplemental real-time 1-min data feed assisted the SPC forecasters by providing more frequent scans of preconvective clouds.

As can be seen in Table 1, GOES-14 data collection continued until September 24, 2012, at 10:14 UTC when GOES-14 was needed for the operational service during a major anomaly (outage) of GOES-13. From that moment until GOES-13 was restored to service October 18, GOES-14 operated as the operational east satellite. “The root cause of the GOES-13 anomaly unusual large Filter Wheel vibration as the root cause for the sounder east/west scan motor overload. The large vibration disturbance was further transmitted onto the imager/sounder optical bench which was also affecting imager East/West scan control system.” (NOAA National Environmental Satellite, Data, and Information Service (NESDIS) memo: “GOES-13 Anomaly Report—September 23, 2012 Imager and Sounder Instrument Scan Motor Overload,” January 2013).

After GOES-13 returned to operations, the 1-min imaging from GOES-14 was not resumed. As Hurricane Sandy neared Jamaica, track forecasts increasingly suggested an impact with the United States East Coast was imminent. At the suggestion of researchers at CIMSS and NOAA NESDIS in Madison, Wisconsin, a request was sent to satellite operations warning of an “epic storm along the east coast” the following week. At this time, GOES-14 was slated to be placed back in storage mode within a few hours, when the request for special 1-min data from the GOES-14 imager of Hurricane Sandy through landfall was approved. NOAA NESDIS OSPO restarted the 1-min special SRSOR scans within 24 h. During the SRSOR time frame in 2012, GOES-14 collected approximately 30,000 images (or over 500 GB).

The SRSOR animations give the best representation to date of what the routine mesoscale imaging from the ABI will be like. NOAA had never before operated a GOES in continuous 1-min mode, from a consistent orbit for so long a period, making this an unique dataset. Animations of visible and infrared (IR) imagery at 1-min intervals provide a unique perspective of atmospheric and other environmental phenomena. A viewer can witness the dynamic nature of the atmosphere as seen from space and watch as features develop and eventually dissipate or move out of the scene. The high-temporal resolution of these stunning images provides scientifically valuable information that researchers are currently studying.

Convection

The effect of “varying temporal sampling” was investigated in relation to several severe storms, showing the importance of rapid scanning, given that “storms evolve significantly on time scales shorter than the current GOES operational scan strategies.”10 Many applications regarding severe weather will benefit from more rapid imaging.11

The GOES-14 imager captured convection developing extremely rapidly over Missouri and Arkansas on August 16, 2012, the first day of the SRSOR experiment (Fig. 3). A time sequence of 90 min of 10.7-μm IR window channel imagery demonstrates the rapid convective development of the storm in Arkansas circled in Fig. 3 and magnified in Fig. 4. Note the cold cloud top pixels associated with over shooting cloud tops. The corresponding high-temporal (1 min) resolution animation shows rapidly developing convection over the region (Video id1). According to the NOAA Storm Reports, the storm in Fig. 3 had a severe wind report with it at 18:27 UTC (“A tree was blown down onto Highway 10”). The NOAA Storm Reports for this day from the SPC can be found at http://www.spc.noaa.gov/climo/reports/120816_rpts.html.

The cloud top rapid cooling for the storm circled in Fig. 3 as seen in the 1-min data is not well represented when the data are subsampled in time to represent operational RSO (blue line) or normal operations (red line) (Fig. 5). The cloud-top emissivity (ordinate) represents the cloud compared to an optically thick cloud at the tropopause, where the emissivity “εtot is a measure of how close the cloud radiative center is to the tropopause.”10 This higher time resolution is especially important when monitoring rapidly developing storms. The time change in εtot can be interpreted as a cloud-top cooling rate.

On September 08, 2012, there was an EF0 tornado reported in the Queens borough of New York City at approximately 15 UTC: http://www.spc.noaa.gov/climo/reports/120908_rpts.html. GOES-13 (operational GOES-East at the time) also viewed this cell. Unfortunately, the touch-down occurred when GOES-13 was performing a routinely scheduled full-disk image and only collected imagery at 14:45 UTC, 15:15 UTC, and 15:45 UTC (housekeeping on GOES-13 was performed for 10 min starting at 15:34 UTC). Nevertheless, the animation of the visible and IR imagery shows the development of the tornadic cell along the convergence line. The 30-min gap between images, however, makes computation of convective predictors complementary to radar such as cloud-top cooling ineffective. GOES-14 was in SRSOR on September 8, and its (almost) every minute imagery captured the evolution of the tornadic cell very well. The 1-min imagery allows careful scrutiny of the cloud-top temperature as the cells evolve. The loop, from 14:45 UTC to 15:09 UTC, spans the time of tornadic activity, and the initial cloud-top cooling and subsequent anvil spreading is readily apparent (Video id2). Note that the GOES-13 is animated with the normal time between images (15 or 30 min), while the GOES-14 is in SRSOR (Video id3).

Total lightning flash detections from northern Alabama Lightning Mapping Array (NA-LMA) and Earth Networks Total Lightning Network (ENTLN) were monitored at 1-min intervals within 15 km of the center of an overshooting cloud-top producing storm cell south of Huntsville, Alabama, on September 2, 2012 (Fig. 6). OTs were detected by the GOES-R algorithm for 30 consecutive GOES scans, though an OT was evident in visible imagery prior to 23:33 UTC. Radar vertically integrated liquid (VIL) and enhanced echo top height were analyzed from the Huntsville and Birmingham, Alabama, Weather Surveillance Radar 1988, Doppler. The ENTLN network did not transmit valid data for 3 min from 00:00 to 00:03 UTC (i.e., 24:00 to 24:03 on the ordinate) on the 3rd. Lightning activity began to increase in association with (1) IR cloud-top cooling and ascending cloud top height and (2) an increase in radar echo top height and VIL. The NA-LMA and ENLTN lightning time trends follow each other quite well. Lightning maximized near the time of a severe wind report at 23:56 UTC. The minimum IR brightness temperature (BT) preceded the maximum flash rate by approximately 7 min, though a secondary maximum in echo top and IR BT occurred at the time of severe wind. Although detection of continuous OTs for an extended period did not clearly indicate a particular time of significant weather, the combined presence of continuous OTs, high/increasing VIL, and high/increasing flash rate may be indicative of impending high impact weather and may improve the forecaster’s situational awareness.

Fires/Biomass Burning

The geostationary perspective allows one to monitor the diurnal signatures of a number of phenomena, including wildfires. The SRSOR is a great improvement over the operational RSO (12). The “start” of a fire is observed in both the visible loop (Video id4) and shortwave IR window loop (Video id5). Both spectral bands also show the smoke plumes from the fires. It should be noted that the BT of some fires is fairly constant over time, while other fires have widely varying BTs. Of course rapid scan images of fires can help monitor these changes and understand how they are associated with changes of wind speed/direction, moisture, fuel loads, etc. This may have implications in air quality models, to make sure the fire properties that are being assimilated are not aliased. How the same fire can rapidly change is demonstrated with GOES-12 RSO from 15:15 UTC May 9, 2007, to 04:15 UTC May 11, 2007. This is from the Bugaboo-Scrub fire in Georgia, USA. As can be seen in Fig. 7, the BT of the 3.9-μm band varies tens of Kelvin over just minutes. The 10.7-μm band does not show these rapid changes. The 3.9-μm band saturates at approximately 342 K for this imager, yet the similar band on the ABI at will be increased to 400 K. So, the ABI will improve not just the dynamic range, but also the spatio-temporal attributes.

Hurricanes

GOES-14 SRSOR imagery of four tropical cyclones were acquired in 2012: Helene, Isaac, Leslie, and Sandy. Due to the many days of SRSOR data and the catastrophic impact of Hurricane Sandy on the most populous areas of the east coast of the United States, this case is of the most interest. The multiday 1-min interval scans were collected during Hurricane Sandy, from October 25, 2012, at 17:45 UTC to October 31, 2012, at 22:41 UTC, roughly centered on the storm. Each afternoon the expected coordinates of the storm for the following day were communicated by NOAA NESDIS scientists to the satellite operators for subsequent data collection (Fig. 8).

The SRSOR scans from the GOES-14 imager were the most rapid scan images of a hurricane ever recorded (Video id6). Over 7000 images of Hurricane Sandy were acquired from GOES-14. The loops were shown on the Weather Channel, CNN, NBC, Reuters, and other media outlets, in addition to being used experimentally by NOAA [including OPC, Weather Prediction Center (WPC), NHC, NWS Eastern Region, and NWS Southern Region]. Some of the loops were also posted on YouTube and collectively received over 1 million views. A high-definition YouTube animation of the visible band during daylight hours was posted: http://youtu.be/f2tPHiMAB5U?hd=1 and http://youtu.be/p72XhZT6KdA?hd=1 (the second link is set to play the loop back in 1 min).

The coverage location varies each day following the storm. The animation of the visible band (Video 6) only shows the sunlit hours. On several of the days, the hurricane animations depict wind shear of approximately 180 deg. A more detailed analysis of Hurricane Sandy can be found in Folmer et al.13

These nonoperational GOES-14 data of Hurricane Sandy were not acquired by the Comprehensive Large Array-data Stewardship System (CLASS) in real time. So that these unique datasets might be more widely available, the Space Science and Engineering Center (SSEC) Data Center transferred the GOES Variable (GVAR) data to the CLASS. The total amount of Hurricane Sandy data transferred was on the order of 98 GB. These data, along with other SRSOR data from both 2012 and 2013, can be accessed at CLASS or the SSEC Data Center or other sites.

Smoke/Cloud Interactions

While super rapid scan information is most needed to monitor convection that can provide earlier warning for severe weather, it is also useful for monitoring the complex interaction between many other phenomena, such as smoke, clouds, and precipitation. One example shows smoke that appears to suppress the growth of a cumulus cloud field because it reduces the solar insolation necessary to force the convection (Video id7). Smoke is also hypothesized to affect the microphysical processes within clouds, leading to a decrease in precipitation efficiency.14

The example in Video 7 highlights how unique 1-min imagery provides visual evidence of what is happening physically in the atmosphere and allows scientists to visualize fine-scale motions. With 15-min imagery, it is difficult to visualize how the smoke interacts with the cumulus cloud field, but in Video 7 the interaction becomes more obvious and provides scientists with a unique perspective.

A goal during the GOES-R ABI era will be to effectively harness the information from the rapid scan imagery, without requiring forecasters and others to necessarily look at each image/loop. Stated another way, the information from the rapid scan imagery must be extracted, not just the data provided. This can be accomplished via smart decision aids such as those being demonstrated in the GOES-R Proving Ground.4 For example, the rate of a rapidly cooling cloud top can be used to infer the convections’ subsequent intensity.15 The improved satellite information from the ABI will lead to improvements for many derived products. One such example is the greatly improved atmospheric motion vectors (AMVs) that higher time resolutions allow.16 Low-level (700 to 950 hPa) vectors have been derived from time sequences of visible band data using the current GOES algorithm (Fig. 9). The AMVs are derived from visible imagery, the delta times (between the first and middle images) are 7.5 and 1 min, respectively. So, the images span 15 and 2 min, respectively. The circulation of the hurricane is better defined with the GOES-R higher time resolutions. There are more than an order of magnitude more AMVs for this case/region. Another example will be better monitoring of OTs associated with tropical cyclones.17 This recent work with rapid scan imagery builds on that of earlier work with GOES-9.18

AMVs from three images 7.5 min apart (GOES sampling) are shown on the left panel, while AMVs from three images that are 1 min apart (mesoscale GOES-R-like sampling) are on the right panel. The images are from Hurricane Sandy, nominally at 18 UTC on October 26, 2012.

The GOES-R will also have a GLM to monitor total lightning activity.6 Signatures in the cloud top observed and objectively detected in GOES-R ABI visible and IR imagery will be combined with GLM total lightning observations to better understand dynamical processes occurring within convective storms and improve severe weather forecast lead time. The GLM will map total lightning activity continuously day and night with near-uniform storm-scale spatial resolution of 8 km with a latency of <20s from flash detection to distribution to user. The GLM will monitor most of the Americas and adjacent oceanic regions in the western hemisphere. As can be seen in Video id8, objectively detected overshooting cloud tops are often found within clusters of in-cloud and cloud-to-ground lightning flashes and occur in advance of severe weather reports.19 Aviation turbulence observations at high-temporal resolution overlaid upon the SRSOR imagery illustrate that numerous light and moderate intensity events occur as aircraft fly within the outflow of, and gravity waves are generated by, deep convection.

The acquisition of experimental 1-min SRSOR data during the fall of 2012 from GOES-14 provided a unique opportunity to observe many phenomena at high time resolution, including, but not limited to, clouds, convection, fires, smoke, and hurricanes (including Hurricane Sandy). Even while the GOES-14 SRSOR data were experimental, this rapid-scan imagery was shown to have great potential in the operational arena, especially in the area of severe weather monitoring and nowcasting. The animations themselves will help the forecasters to subjectively monitor the progress and structure of convective cell growth and behavior. Many quantitative products will benefit from the rapid 1-min refresh. For example, the OTs, cloud-top cooling rate, AMVs, and turbulence products should all improve in quality and use from a regular rapid-scan schedule. Examples from the SRSOR data included better determining the cyclone center early in the daylight hours by the NHC, improved monitoring of cumulus cloud fields prior to convective initiation by the SPC, utilizing the imagery animations and derived AMVs by the OPC, identifying meso-high locations associated with hurricanes to better assess the rainfall potential by WPC, monitoring smoke plumes by the Satellite Analysis Branch, and OT detection by the forecast offices. Many other possible applications can be utilized in the GOES-R era with high time resolution data from the ABI. The SRSOR data have allowed researchers and operational forecasters to better understand the potential for routine rapid scan imagery, shown either as animated loops or derived products. Many of the rapid scan derived products in the GOES-R era should be valuable to the next generation of real-time/rapid-update-cycle mesoscale data assimilation and high-resolution modeling. These data could be assimilated in forecast models or used to validate model outputs.

The SRSOR digital datasets, in a number of formats, are available in their entirety from several organizations, for example, at CLASS: http://www.class.noaa.gov or the SSEC Data Center (http://www.ssec.wisc.edu/datacenter). These unique data will be used for years to better prepare the United States and others for the improved time resolution of the ABI on GOES-R.

The authors would like to thank the many contributors to the generation of the GOES-14 SRSOR imager data streams. NOAA NESDIS OSPO is especially thanked for the production of the GVAR data. Thanks to: Kathy Kelly, Kevin Ludlum, GOES shift supervisors and operators, John Tsui, Hyre Bysal, Tom Renkevens, Bill Bellon, Tim Olander, Jim Nelson, Pete Pokrandt, Justin Sieglaff, Dave Radell, Frank Alsheimer, Andy Edman, Natalia Donoho, Matthew Seybold, Ryan Rogers, Lawrence Carey, Cecilia Fleeger, Wayne Feltz, Sarah Monette, Don Hillger, Gary S. Wade, Jay Hoffman, Elaine Prins, Michael J. Folmer, Jordan Gerth, Chad Gravelle, Pam Heinselman, David Priegnitz, and Daniel Karlson. Discussions with Ralph Petersen during the 2011 Warn on Forecast-High Impact Weather Workshop in Norman, Oklahoma, led to the idea to acquire high time resolution imagery for comparisons to the phased array radar. Special thanks go to Jerry Robaidek and the SSEC Data Center staff (Janean Hill, Roseann Spangler, Dave Jones, Doug Ratcliff, etc.) who acquired the GOES-14 data at the SSEC Data Center and handled the switchover between GOES-13 and GOES-14 when GOES-14 temporarily became the operational GOES-East. Dave Stettner is thanked for his assistance with Fig. 9. The SSEC Man computer Interactive Data Access System (McIDAS) was used to create most of the images.
