HS3 Hurricane Atmospheric Profiles from High-Altitude Radiometer

Measurements from the High Altitude MMIC Sounding Radiometer (HAMSR) instrument aboard NASA's Global Hawk aircraft during the Hurricane and Severe Storm Sentinel (HS3) campaign. The dataset provides 25-channel microwave radiometry data to infer 3D atmospheric profiles of temperature, water vapor, and cloud liquid water, even in cloudy conditions. It is managed by the GHRC DAAC and available in netCDF/CF format.

Use Cases

• Analyzing the 3D distribution of atmospheric temperature using the 53-GHz band channels.
• Profiling water vapor and humidity via the 183-GHz band measurements.
• Assessing cloud liquid water content and scattering effects with the 118-GHz band.
• Studying the impact of the Saharan Air Layer (SAL) on tropical storm dynamics.
• Investigating inner-core deep convection processes in hurricanes.

Strengths

• Data captures 25 spectral channels across three specific microwave bands for detailed atmospheric profiling.
• Measurements are designed to infer profiles even in the presence of clouds, enhancing utility for storm analysis.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating recognized importance.

Limitations

• Specific row count, file size, and exact column names are not provided by any source.
• Sources conflict on license details, with one listing 'other-license-specified' and another 'None'.
• Author information is consistently listed as unknown or None.
