Abstract: A method is described for the objective determination of the noise level in Doppler spectra. The method makes use of the physical properties of white noise and is suitable for automatic computation. It is shown that the ...

Abstract: Data obtained in a thunderstorm with a vertically pointing Doppler radar are analyzed to find the size distribution of raindrops at heights below the 0C level. Drop-size distributions were computed using the updraft UR ...

Abstract: Some general properties of exponential particle-size distributions are discussed. Especially significant are the corrections to calculated liquid water content, precipitation rate, radar reflectivity, and median volume ...

Abstract: The concentrations of hygroscopic and non-hygroscopic aerosols in large and giant size ranges were measured at Delhi in different periods during 1960?62. The content of ice-forming aerosols also was estimated simultaneously ...
