IMPACTS Campaign Surface Weather Data for Atlantic Snowstorms

Two Stony Brook University weather stations in New York City collected surface meteorological data during the three-year IMPACTS field campaign from 2020 to 2023. The dataset contains variables such as temperature, dew point, humidity, air pressure, and wind speed and direction. It was produced by the GHRC DAAC to study the microphysics and formation mechanisms of snowstorms along the U.S. Atlantic Coast.

Use Cases

• Analyzing temporal trends in surface temperature and air pressure during snowstorm events.
• Correlating wind direction and speed measurements with snowband organization and evolution.
• Studying humidity variables (relative, absolute, mixing ratio) to understand microphysical characteristics of snow particles.
• Using dew point and temperature data to examine near-surface atmospheric conditions in winter storms.
• Integrating station data with other IMPACTS campaign observations for multi-instrument analysis of precipitation mechanisms.

Strengths

• Data covers a multi-year time range from January 1, 2020, through January 25, 2023, capturing multiple winter seasons.
• Measurements come from two distinct station types (one mobile radar truck, one stationary site), providing spatial context.
• The dataset is available in both netCDF-4 and ASCII-CSV formats, supporting different analysis workflows.

Limitations

• The exact row count and dataset size are not specified on any platform, limiting assessment of data volume.
• Sources conflict on license information: one lists 'other-license-specified' while another states 'None'.
• The complete list of column names is not provided, requiring users to inspect files to understand the full data structure.
