Abstract : Gridded ESSA 5 and 7 and ATS-3 satellite data for selected 1968 dates are analyzed in conjunction with gridded MIAC WSR-57 radar data to determine the percentage of cloud area covered by radar echo in South Florida. It is found that the percentage tends to increase with increasing convective regime number. Also, the highest percentage occurs progressively further inland as the regime number increases. DAPP visible, DAPP IR and ATS-3 visible satellite data on eleven September 1973 dates are analyzed using color densitometer techniques and correlations are made with radar and other meteorological data to gain insight into relationships between satellite, radar, ceiling height and surface visibility data in South Florida. It is shown that the correlation coefficients are dependent upon location of the data with respect to the coast and with respect to the type of convective regime. Radar echo area conrrelates best with the DAPP IR cloud area at 18,000 feet and at 30,000 feet. On the average, radar echoes occupy 42 percent of the cloud area at those altitudes. (Author)
