Satellite Remote Sensing of the Wet Bulb Globe Temperature Heat Stress Index. Phase 2
Abstract
The Wet Bulb Globe Temperature (WBGT) is the basic parameter used by the U.S. Army to quantify heat stress. The index is computed as a weighted sum of dry bulb, wet bulb and black globe temperature measurements. During 1985, Gulf Weather Corporation received a Small Business Innovation Research (SBIR) phase I contract form the U. S. Army Research Institute of Environmental Medicine to determine if the WBGT could be determined from information routinely available from U.S. weather satellites. Phase I efforts demonstrated relationships between dry bulb temperature and AVHRR data and between wet bulb temperature and the total precipitable water derivable from TOVS data available from NOAA satellites. Algorithms for these relationship were developed. Phase II of the research was initiated in June 1987. Additional ground truth data were collected for further refinement of these algorithms. Data were collected in arid regions of the southwestern United States. Additional data for moist, vegetated areas will be collected in the summer of 1988.
