On the influence of the vertical variability on the Earth-to-satellite communication link rain retrievals
Creators
Description
In the last two decades, several studies exploited opportunistic microwave signals to improve precipitation estimation capability. In this framework, the Nefocast project developed an ad-hoc algorithm to retrieve precipitation from the attenuation experienced by Earth-tosatellite links and deployed an extensive field campaign to validate the algorithm. Thanks to the co located measurements of a satellite receiver (SmartLNB), a disdrometer and weather radar in Rome, several assumptions of the Nefocast algorithm were addressed. Recently a vertically pointing micro rain radar (MRRPRO) was added to the Rome set-up allowing the analysis of the variability of the precipitation and its possible influence within the Nefocast algorithm. The preliminary results showed that the vertical variability of precipitation can play a role in the Nefocast estimates.
