HAMSR CPEX-CV: Atmospheric Profiles from Microwave Radiometry

25 spectral channels across 3 bands provide measurements from the High Altitude MMIC Sounding Radiometer (HAMSR) instrument. The dataset was collected during the NASA CPEX-CV field campaign aboard a DC-8 aircraft from September 6-30, 2022, based out of Sal Island, Cabo Verde. It contains inferred profiles of temperature, water vapor, and cloud liquid water, designed to investigate atmospheric dynamics in the tropical East Atlantic.

Use Cases

• Infer 3-dimensional temperature profiles based on microwave radiometry measurements.
• Analyze water vapor distribution in the atmosphere, even in cloudy conditions, based on spectral channel data.
• Study cloud liquid water profiles to understand cloud microphysics and precipitation processes.
• Investigate interactions between the marine boundary layer and the dust-laden Saharan Air Layer based on campaign objectives.
• Validate and improve atmospheric models for the tropical East Atlantic region based on field campaign measurements.

Strengths

• Data covers a specific field campaign period from September 6-30, 2022.
• Instrument has 25 spectral channels split into 3 bands for detailed atmospheric profiling.
• Campaign was designed with specific scientific goals to investigate atmospheric dynamics, convection, and boundary layer properties.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is available only for a limited time range of approximately 25 days.
