Abstract
The sensitivity and spatial resolution of the NEXRAD system offers the promise of accurate measurement of precipitation in real time. Since the radar provides more spatially detailed and frequent measurements, it should improve rain measurements. In this connection, a cooperative study of the National Weather Service Chicago office and Northern Illinois University, with assistance from the Illinois State Water Survey, was conducted. The objective is to compare precipitation measurements from rain gages with accumulated precipitation estimated by the Precipitation Processing Subsystem (PPS) of the WSR-88D, and to determine the conditions under which the radar and gage measurements are matched, and under which they diverge. It is shown that the comparison was poor when either the radar or the gage reported small amounts; often the radar reported zero amount when the gage reported a measurable amount. Therefore, data pairs were excluded when either gage or radar reported less than 0.1 inch per storm.
