Analysis of the Ability of Infrared Water Vapor Channel for Moisture Remote Sensing in the Lower Atmosphere

The ability of HIRS / 2 and GOES 1 / M infrared water wapor channels for moisture remote sensing in the lower atmosphere has been analyzed. It is found that the HIRS / 2 channel 10 seems not to be an optimal channel for water vapor remote sensing in the lower part of the atmosphere, we can find other channels that are more sensitive to mois-ture variation in the lower atmosphere and might be more useful for low level atmospheric moisture remote sensing.
