VIPR
Vapor Inside-cloud Profiling Radar

The Vapor Inside-cloud Profiling Radar (VIPR) is an airborne differential absorption radar developed at the Jet Propulsion Laboratory (JPL). It retrieves absolute humidity inside clouds and precipitation and column-integrated water vapor profiles. It operates across the three frequencies in the G-band: 158.6, 167.12, and 174.74 GHz. VIPR provides water vapor profiles every 1.9 seconds and has a nominal range resolution of 15 meters.
