INVESTIGATION OF THE QUANTITATIVE DETERMINATION OF PRECIPITATION BY RADAR.
Abstract
The results of two years of radar measurement of rainfall amounts over the Kankakee rain gage network has shown that the accuracy is not greatly different than the accuracy over the much closer East Central Illinois network. In either case if the standard error of estimate of radar amounts is chosen as a measure of the error, a result of about 0.2 inch for storm total is obtained. Results of preliminary study of extrapolation of radar rainfall equations to other parts of the world is reported. A method depending upon the percentage of rain days which are thunderstorms and the relative humidity at a level of 0.5 km has been tentatively chosen. A survey report on the relationships between rainfall rate and radar reflectivity in the measurement of precipitation shows that the relationships introduce less uncertainty than the errors in present day radar measurement of reflectivity.
