Description
August 17 to September 4, 2021 data from the High Altitude MMIC Sounding Radiometer (HAMSR) instrument, collected during the NASA/ESA Convective Processes Experiment – Aerosols & Winds (CPEX-AW) field campaign. The dataset provides 25 spectral channel measurements across three bands, enabling inference of 3D atmospheric profiles for temperature, water vapor, and cloud liquid water from the NASA Global Hawk aircraft. It supports calibration and validation activities for the ADM-AEOLUS wind Lidar satellite.
Use Cases
Calibrating and validating satellite-based wind measurements from the ADM-AEOLUS Lidar using co-located atmospheric profiles.
Analyzing 3D distributions of atmospheric temperature and water vapor over the tropical Atlantic.
Studying cloud microphysics and liquid water content in convective systems.
Investigating the relationship between aerosols, winds, and convective processes during the CPEX-AW campaign.
Strengths
Data is from a focused 19-day NASA/ESA joint field campaign with a clear calibration/validation objective for a major satellite mission.
The HAMSR instrument provides 25 spectral channels across 3 bands, allowing retrieval of multiple atmospheric variables even in cloudy conditions.
Measurements are geolocated and time-stamped from the NASA Global Hawk aircraft, providing detailed spatial and temporal coverage for the campaign period.
Limitations
Key technical details like row count, file size, and specific column names are not provided across any platform.
The license is listed as 'other-license-specified' on Data.gov but is 'None' on NASA Earthdata, creating a conflict requiring user verification.
