simple retrieval by mutliple regression problems with smaller rain water path amounts

Summary & Outlook cloud radar and selected microwave frequencies seems to have interesting information content cloud radar and passive microwave components are prepared - to be tested on ground late 2009 belly pod with MW components will be mounted on the aircraft 2010 first missions

Thanks!
