    • Rapid X-band Polarimetric Radar (RaXPol) IMPACTS

    Metadata Updated: April 9, 2026

    The Rapid X-band Polarimetric Radar (RaXPol) IMPACTS dataset consists of data measured from the RaXPol instrument during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S. Atlantic coast. IMPACTS aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The RaXPol dataset consists of various reflectivity variables. RaXPol data are available from January 29, 2022, through January 25, 2023, in netCDF-4 format.
