Utility of Radar in Measuring Areal Rainfall *

Abstract

Areal rainfall distribution over a 50-square-mile area was observed by 3-cm radar and by a rain-gage network of 33 rain gages. Isohyetal maps were prepared from both rain-gage and radar observations in order to compare the rainfall distribution as observed by the two rainfall observation techniques. The computed rainfall values were at least as accurate as those obtained by a rain-gage network of one gage per 200 square miles and in some cases they were considerably more accurate.

“…Important early papers include those on rain drop size distributions (Marshall & Palmer, 1948) and shapes (Browne & Robinson, 1952;Hunter, 1954;Newell et al, 1955), the measurement of precipitation (Ryde, 1946;Byers, 1948;Bowen, 1951;Twomey, 1953;Battan, 1953;Stout & Neill, 1953), its vertical structure (Langille & Gunn, 1948) and associated estimation errors (Hitschfeld & Bordan, 1954), and those on thunderstorm identification, behaviour and dynamics (Wexler & Swingle, 1947;Byers & Braham, 1949;Wexler, 1951;Ligda, 1951;Battan, 1953).…”

A Comparison of Gauge and Radar‐Derived Rainfall in a Land Falling Typhoon in Taiwan1

“…Stout and Neill (1953) first used 33 gauge measurements to correct radar reflectivity for estimating precipitation. Traditionally, surface rainfall measurements from rain gauge data are typically used as a standard reference for correcting radar data.…”

“…Numerous studies have experimented with a combination of two sensors, radar data and rain gauge data. Stout and Neill (1953) first used 33 gauge measurements to correct radar reflectivity for estimating precipitation. Joss et al (1968) used radar reflectivity with a wavelength of 4.6 cm to calculate precipitation amounts; they proposed Z = 300R 1.5 to regress rain gauge measurements and radar reflectivity.…”
