Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment

The Campaign

The Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WHyMSIE) was a field investigation between NASA and NOAA. It studied the thermodynamics and evolution of the planetary boundary layer (PBL) to improve PBL observations for Earth Science and to work towards building a PBL observing system of systems. WHyMSIE occurred from October to November 2024 across the western United States and Great Plains. The NASA ER-2 was equipped with a suite of instruments, including the Conical Scanning Millimeter-wave Imaging Radiometer - Hyperspectral (CoSMIR-H), Airborne Radio Occultation (ARO), and Microwave Barometric Radar and Sounder (MBARS) to collect profile measurements of temperature, winds, water vapor, and cloud properties. A companion experiment for validation, the Active and Passive Profiling EXperiment (APEX), also deployed the High Altitude Lidar Observatory (HALO) and Aerosol Doppler Wind Radar (AWR) on board the G-III aircraft. WHyMSIE flew over ARM Southern Great Plains (SGP) Central Facility (CF) for ground-based validation data. WHyMSIE was funded through NASA's Earth Science Technology Office (ESTO) and the Decadal Survey Incubation (DSI) Program.
