MRMS Radar Reflectivity for Atlantic Coast Snowstorms

Data from January 1, 2022, through March 2, 2023, provides radar reflectivity products for studying winter snowstorms along the U.S. Atlantic Coast. It was generated by the Multi-Radar/Multi-Sensor (MRMS) system during the three-year IMPACTS field campaign. This dataset supports research into snowband formation, microphysics, and remote sensing validation.

Use Cases

• Analyzing the spatial structure and evolution of snowbands using radar reflectivity fields.
• Validating satellite-based precipitation products against ground-based radar observations.
• Studying microphysical growth mechanisms of snow particles within Atlantic Coast storms.
• Improving numerical weather prediction model parameterizations for snowfall.

Strengths

• Data originates from the authoritative MRMS system, a high-resolution national radar network.
• Covers a specific 14-month period during a dedicated, multi-year field campaign (IMPACTS).
• Available in the standardized, self-describing netCDF-4 format for scientific analysis.

Limitations

• Specific column names and the dataset's row/record count are not provided by any source.
• Sources conflict on license details, with one listing 'other-license-specified' and another 'None'.
• The exact spatial resolution and geographic bounds of the data are not detailed.
