Book Description
SSH data from the Defense Meteorological Satellite Program were received for analysis and evaluation. Valuable inherent water vapor information is contained in the eight DMSP Water Vapor Channels that operate in the 18-30 micrometer rotational water vapor band. Middle and/or high tropospheric cloudiness may be determined by analysis of the spectral radiances measured by the various DMSP water vapor channels. Clear or cloudy conditions may be determined by analysis of the slope of the spectral radiance of only three DMSP SSH Channels. (Author).

A Ground Truth Analysis of DMSP Water Vapor Radiances

Pages : 52
Book Description
SSH H2O data from the Defense Meteorological Satellite Program (DMSP) were received for analysis and evaluation. Approximately 70 measurements of upwelling radiation in the 8-sounder channels of the 18 to 30 micron rotational water vapor band have been compared with calculations for both clear and cloud contaminated conditions. The calculated radiances generally exceed the measured radiances in the clear column comparison. In the mean, the radiance comparison indicates a discrepancy less than 5 percent in the water vapor continuum band. This systematic discrepancy, by approximately a 4:1 ratio, is found in all the DMSP SSH H2O channels. These results are in agreement with McClatchey's 1976 results in his analysis of the DMSP 15 micron CO2 sounder channels. The data sets comparison were divided into three latitude belts, that is, Tropical, Mid-latitude and Arctic. In turn, the discrepancies between calculated and measured radiances appear to be latitudinally dependent. Smaller discrepancies are found in the Tropics and the larger discrepancies are found in the Arctic latitude belt. Also, it appears that the DMSP SSH H2O channels cannot discriminate between low cloud contamination and clear column conditions.
