Description:

"This note presents the results of a preliminary evaluation of VAS (VISSR Atmospheric Sounder) data for two cases, 12 GMT 14 April and 12 GMT 15 April 1981, hereafter referred to as Cases A and B, respectively. Section 1 presents discussions of both the synoptic conditions during these cases, and the results of comparing VAS temperature soundings with those from radiosondes. Section 2 discusses the differences between layer thicknesses derived from VAS and those derived from various NMC analysis and forecast systems. Finally, section 3 presents LFM analyses made with and without VAS data. The soundings for Cases A and B were made in the dwell sounding (DS) mode of the VAS radiometer (Smith, 1981). Table 1 summarizes the characteristics of the VAS radiometer in the DS mode"--Introduction.
