NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) has released Version 2 of the CoSMIR-H WHyMSIE airborne dataset, providing calibrated and geolocated brightness temperature observations collected during the October-November 2024 field campaign.
The Conical Scanning Millimeter-wave Imaging Radiometer-Hyperspectral (CoSMIR-H) WHyMSIE V2 dataset delivers multi-frequency (50–191 GHz) microwave brightness temperatures that are used to derive atmospheric temperature profiles, water vapor, cloud properties, and precipitation rates. These hyperspectral microwave observations support planetary boundary layer (PBL) research and improve understanding of atmospheric structure across diverse surface and weather conditions, while also informing future satellite mission design and retrieval algorithms.
Version 2 builds on earlier CoSMIR airborne datasets by incorporating WHyMSIE campaign observations and updated calibration/geolocation—extending heritage CoSMIR measurements into hyperspectral capability that better aligns with next-generation microwave sounding missions.
