Abstract

This paper investigates the approaches of Saharan dust storm detection with the Moderate Resolution Imaging Spectroradiometer (MODIS) thermal infrared bands and presents an index, thermal-infrared dust index, through quantitative analysis of MODIS data for major dust events over the Atlantic Ocean during year 2004-2006. It is found that aerosol optical thickness (AOT) at 550nm has close relationships with the brightness temperature of MODIS bands 20, 30, 31, and 32. The proposed thermal-infrared dust index matches MODIS AOT very well with a squared correlation coefficient of 0.7646. Case study and statistical analysis suggest the potential to use 1km thermal-infrared dust index data for detecting dust storms and evaluating the potential impacts of regional weather, such as Atlantic hurricanes, and climate in the near future.
