Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment

The Campaign

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