An interactive system for compositing digital radar and satellite data.

Abstract

Describes an approach for compositing digital radar data and GOES satellite data for meteorological analysis. The processing is performed on a user-oriented image processing system, and is designed to be used in the research mode. It has a capability to construct PPIs and three-dimensional CAPPIs using conventional as well as Doppler data, and to composite other types of data. In the remapping of radar data to satellite coordinates, two steps are necessary. First, PPI or CAPPI images are remapped onto a latitude-longitude projection. Then, the radar data are projected into satellite coordinates. Examples of PPI and CAPPI data composited with satellite data are given for Hurricane Frederic on 13 Septmber 1979 and for a squall line on 2 May 1979 in Oklahoma. -from Authors
