Abstract

A new approach to measuring wind and temperature is under development that could revolutionize our ability to monitor wind and neutral temperature in the upper atmosphere. Using a Doppler modulated gas filter correlation technique, wind and temperature can be measured simultaneously from low Earth orbit, continuously from 15 km to over 200 km, on one second time intervals, both day and night. A constellation of six of these dual-sided Doppler Wind and Temperature Sensors (DWTS) on small-sat platforms could provide nearly real time global temperature and wind fields. The DWTS technique, measurements and weather forecast benefits are discussed.
