An Algorithm to Retrieve Water Vapor Information from Satellite Measurements.

Abstract

Radiance values for the eight water vapor channels on the DMSP/SSH infrared sounder were simulated for cloud free conditions. The simulated values were inverted using a statistical multiple regression procedure to estimate total precipitable water. Inversions were also obtained using both the infrared water vapor channel data and temperature profile data. For the sounder channels incorporated into the DMSP/SSH sensor package, profile measurements are not possible below the height of the tropopause using the infrared channel data alone. Successful inversions with more than an 80 percent reduction of variance from climatological values were accomplished using both temperature profile data (perhaps obtained from the CO2 channel data) and one or more infrared water vapor channel observations.
