NEXRAD Level II Radar Data for Atlantic Coast Snowstorms

31 NEXRAD weather radar sites collected Level II surveillance data from January 1 to March 1, 2020 during the IMPACTS field campaign. The dataset contains meteorological and dual-polarization base data quantities, including radar reflectivity, radial velocity, and differential phase, aimed at studying snowband formation and microphysics. Data is provided in netCDF-4 format by the GHRC DAAC and will be updated for subsequent campaign years.

Use Cases

• Analyzing radar reflectivity and radial velocity to study the structure and evolution of snowbands.
• Using differential reflectivity and cross correlation ratio data to examine microphysical characteristics of snow particles.
• Correlating spectrum width and differential phase measurements with storm intensity and precipitation type.
• Model validation and improvement for winter weather prediction along the U.S. Atlantic Coast.

Strengths

• Data originates from a coordinated, three-year scientific field campaign (IMPACTS) with specific research objectives.
• Includes dual-polarization base data from 31 NEXRAD sites, providing detailed meteorological measurements.

Limitations

• Exact file count, dataset size, and total row/volume metrics are not provided by any source.
• Sources conflict on the last updated date, reporting both 2020-03-01 and 2026-03-13.
