SITE-SPECIFIC ANALYSIS OF NEXRAD COVERAGE
With the advent of the Next Generation Radar (NEXRAD) installation by the
National Weather Service (NWS), many older weather radar systems are
being deactivated. Such a process has caused many cities, for weather
radar coverage, to become dependent on NEXRAD stations which are located
at distances of fifty miles or more. The adequacy of such coverage has
become a significant issue. For the cities of Huntsville, Alabama;
Williston, North Dakota; and Evansville, Indiana we have carried out
detailed analyses of the coverage provided by NEXRAD, taking account the
effects of earth curvature, atmospheric refraction, local topography, and
finite beam width. Our analysis carried out for Huntsville is credited
with causing NWS to install a NEXRAD station at Hightop, Alabama to
provide better coverage of the Huntsville area.
