CubeSat Hydrometric Atmospheric Radiometer Mission
 

The Jet Propulsion Laboratory (JPL) and Ames Research Center (ARC) are partnering in the CubeSat Hydrometric Atmospheric Radiometer Mission (CHARM), a water vapor radiometer integrated on a 3U CubeSat platform, selected for implementation under NASA Hands-On Project Experience (HOPE-3). CHARM will measure 4 channels at the 183 GHz water vapor line, subsets of measurements currently performed by larger and more costly spacecraft (e.g. AMSU-B, ATMS and SSMI/S). While flying a payload that supports Science Mission Directorate science objectives, CHARM will provide a hands-on opportunity to develop technical, leadership, and project skills for the team members. CHARM will furthermore advance the technology readiness level (TRL) of the 183 GHz receiver subsystem from TRL 4 to TRL 6 and the CubeSat 183 GHz radiometer system from TRL 4 to TRL 7.
