Mobile UIUC Soundings for Atlantic Snowstorm Research

January 18 through February 25, 2022 atmospheric sounding data was collected by rawinsondes during the IMPACTS field campaign. The dataset provides vertical profiles of temperature, humidity, pressure, and wind to study snowband formation and evolution over the U.S. Atlantic Coast. Data is provided by the University of Illinois at Urbana-Champaign and hosted by the GHRC DAAC.

Use Cases

• Analyzing vertical wind profiles to understand storm dynamics and organization.
• Correlating temperature and relative humidity profiles with snowband formation mechanisms.
• Validating and improving numerical weather prediction models for snowfall forecasting.
• Studying the microphysical characteristics of snow particles across different atmospheric layers.

Strengths

• Data originates from a targeted, three-year NASA field campaign (IMPACTS) focused on snowstorms.
• Provides high-resolution vertical profiles of key atmospheric variables (temperature, humidity, pressure, wind).
• Available in the standardized, self-describing netCDF-4 format for scientific analysis.

Limitations

• Specific row counts, file sizes, and a complete column list are not provided by any source.
• License information is inconsistently reported as 'other-license-specified' or 'None' across platforms.
• The dataset's temporal coverage is currently limited to a single winter season (2022), though updates are planned.
