HAMSR CPEX Atmospheric Profiles from 2017 Field Campaign

High Altitude MMIC Sounding Radiometer (HAMSR) CPEX dataset contains atmospheric measurements from a 2017 airborne field campaign. The instrument's 25 spectral channels across three bands provide data to infer 3D profiles of temperature, water vapor, and cloud liquid water. NASA organized the campaign, which involved sixteen DC-8 missions over the North Atlantic and Caribbean region.

Use Cases

• Analyzing convective storm initiation and dissipation using inferred temperature and water vapor profiles.
• Studying the 3-dimensional distribution of cloud liquid water in the presence of clouds.
• Validating satellite-based atmospheric sounding data with high-altitude airborne measurements.
• Investigating atmospheric conditions in the North Atlantic-Gulf of America-Caribbean Sea region during early summer.

Strengths

• Data originates from a focused NASA field campaign with sixteen dedicated DC-8 flights.
• The HAMSR instrument provides measurements from 25 spectral channels, enabling multi-parameter retrieval.
• Covers a specific, well-documented time period for studying early summer convective processes.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable from all sources.
• Sources conflict on the license: one platform specifies 'other-license-specified' while another lists no license.
• Data format is listed as netCDF-3, but the union of file formats includes ancillary types like BIN, ISO, HTML, and PDF.
