ASOS Ground Observations for Atlantic Coast Snowstorms

176 Automated Surface Observing System stations collected ground-based meteorological data during the three-year IMPACTS field campaign. Observations include surface temperature, dew point, precipitation, wind, pressure, and weather codes from December 29, 2019, through March 1, 2023. The dataset was produced by the GHRC DAAC to study the microphysics and structure of threatening snowstorms.

Use Cases

• Analyzing relationships between surface temperature, dew point, and precipitation type during snowstorm events.
• Studying wind speed, wind direction, and gust patterns associated with the organization of snowbands.
• Validating remote sensing or model data using ground-observed sea level pressure and weather codes.
• Investigating temporal trends in microphysical conditions across 176 stations over three winter seasons.

Strengths

• Data originates from 176 standardized ASOS stations, providing consistent measurement methodology.
• Covers three consecutive winter seasons (2019-2023), capturing multiple storm events for longitudinal analysis.
• Includes key meteorological variables like observed weather code, which categorizes precipitation type.

Limitations

• The exact row count and dataset size are not specified across any platform.
• Sources conflict on the license, with one specifying 'other-license-specified' and another listing 'None'.
