Determination of Precipitation Profiles from Airborne Passive Microwave Radiometric Measurements

摘要: Abstract This study presents the first quantitative retrievals of vertical profiles precipitation derived from multispectral passive microwave radiometry. Measurements brightness temperature (Tb) obtained by a NASA high-altitude research aircraft are related to rainfall rate through multichannel piecewise-linear statistical regression procedure. Statistics for Tb set cloud radiative models representing wide variety convective, stratiform, and anvil structures. The retrieval scheme itself determines which model best fits observed meteorological conditions. Retrieved converted equivalent radar reflectivity comparison with reflectivities ground-based radar. Results two cases studies stratiform rain situation an intense convective thunderstorm, show that radiometrically capture major features structure hydrometeor density.
