Download or read book Snowfall Rates Obtained from Radar Reflectivity Within a 50 Km Range written by Roland J. Boucher and published by . This book was released on 1981 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The snowy winter of 1978 in Massachusetts allowed five opportunities to test the dependability of a CPS-9, 3.2-cm radar to determine snowfall rate and total snowfall accumulation at up to seven measuring sites within 50 km of the radar. Spaced at intervals of 0.5 -to 1-h, 166 snowfall-rate measurements yielded a correlation coefficient of 0.88. However, in correlating the total storm snowfall, the amount of radar-measured snowfall above a reference snowfall measurement site was made equal to the snowfall actually measured at this location. This calibration technique improved the storm snowfall correlation coefficient to 0.96.
