UAlbany Soundings IMPACTS

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: May 26, 2026 at 05:32 PM | Dataset Last Updated: May 18, 2026
The UAlbany Soundings IMPACTS dataset consists of data measured with the iMet-3050A sounding system using 200-g meteorological balloons 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 UAlbany Soundings IMPACTS dataset consists of atmospheric pressure, relative humidity, mixing ratio, wind speed, and wind direction measurements. These data are available from January 5, 2023, through March 1, 2023, in ASCII format.
