Investigation of the Quantitative Determination of Point and Areal Precipitation by Radar Echo Measurements

Résumé du livre

The operational programs for the radars and raindrop cameras are proceeding normally. The M-33 acquisition radar is being used with step gain, at present. The drop cameras have been installed but are not yet ready for data collection. The proposal for measuring radar attenuation and reflectivity to determine rainfall rate is investigated and found to yield no significant gain in estimate reliability. A method for attenuation correction is proposed and evaluated. It appears to be useful for a majority of storms. The 1963 drop-size data from the East Central Illinois Network are presented in brief. Generally no differences in the R-Z relationship for a 2-mile separation of sampling points was found. (Author).
