Book Description
A quasi-objective method for deriving 500-mb geopotential heights with the aid of satellite cloud observations is presented. The method uses satellite-observed cloud patterns in conjunction with a forecast 500-mb height field which is separated into additive short- and long-wave component fields. Empirical relationships between the cloud patterns and the short-wave component field are used to modify the pattern of the latter, and regression equations are used to specify extrema values. The 500-mb heights are retrieved by the direct addition of the modified short-wavelength field to the long-wavelength field. Procedures for using this method operationally are presented, and results of real-time modifications can contribute to significant improvements in the analysis.

Book Description
A verification procedure is applied to determine the accuracy of the Satellite Infrared Spectrometer (SIRS) B temperature retrievals by measuring their usefulness in the context of the National Meteorological Center (Suitland, Md.) operations. Three pressure levels are considered. It is shown that temperatures derived from satellite data for application at 200 mb are definitely useful while at 500 and 300 mb, under certain cloud conditions, the SIRS temperatures are moderately useful.
