FIVE-DIMENSIONAL WEATHER RADAR: GREY SCALE AND CAPPI IN OPERATION, 1959-1962
Abstract
This Final Report is a critical summary of three years' operation of a highly automated CPS-9 and of developments and improvements made during that period. It is contended that the interests of both research and operational users are best served by a weather radar whose operation is as automatic as possible. The radar should provide a display of the precipitation pattern in the space around the radar at regular time intervals. Intensity, over a scale of about 70 db to cover the range of precipitation rates 0.1 to 1000 mm hr(-l) should also be indicated on each display. Since 1955 the main requirement of automatic operation, namely a routine antenna program, has been in use on the McGill CPS-9. From this program we have derived, in a regular time sequence, sets of constant altitude maps to provide three-dimensional coverage of the precipitation. With the addition in 1959 of circuits to display a 64-db range of signals on a stepped grey scale, we added the important dimension of intensity at no expense to the frequency of coverage.
