Description
31 NEXRAD radar sites collected Level II surveillance data from January 1 to March 1, 2020 for the IMPACTS field campaign. The dataset contains dual-polarization base data quantities, including radar reflectivity, radial velocity, and differential phase, to study snowband formation and microphysics over the U.S. Atlantic Coast. It is part of a three-year campaign, with data available in netCDF-4 format and updates planned for subsequent years.
Use Cases
Analyzing snowband formation and evolution mechanisms based on radar reflectivity and velocity data.
Examining snow particle microphysics and growth mechanisms using dual-polarization variables like differential reflectivity.
Improving snowfall remote sensing interpretation and numerical weather prediction models with high-resolution radar observations.
Conducting spatiotemporal analysis of winter storm structure across 31 radar sites on the Atlantic Coast.
Strengths
Contains data from a focused, three-year scientific campaign (IMPACTS) with a clear research agenda.
Includes dual-polarization radar variables from 31 specific sites, providing detailed spatial coverage for the study region.
Data is stored in the structured, self-describing netCDF-4 format, which is standard for scientific data exchange.
Limitations
Column names and exact data structure are not specified in the provided metadata, complicating initial analysis.
Conflicting 'last updated' dates (2026-04-10 vs. 2020-03-01) create uncertainty about the dataset's currency and maintenance.
The license is ambiguously listed as 'other-license-specified' without explicit terms.
