Abstract

Measurements of upwelling thermal emission at 150, 183.3plusmn1, 183.3plusmn3, and 183.3plusmn7 GHz made by the Humidity Sounder for Brazil (HSB) on the Aqua satellite are compared to calculated brightness temperatures. Atmospheric temperature and moisture profiles were obtained with research-quality radiosondes launched coincident with Aqua overpasses from several locations in various climates. In addition to water vapor, the calculations included minor amounts of absorption by nitrogen, ozone, and oxygen. Mean differences (measurement- calculated T_B) for the four channels range from -0.17 to -0.42 K.
