New York State weather-station network (winter storms study)

New York State Mesonet IMPACTS
atmosphere NASA GHRC_DAAC Level 3 PNG
In plain English

What it measures. Standard ground-weather readings across New York State, including temperature, wind, pressure, precipitation, and snow depth, plus vertical profiles of the air from laser and microwave instruments.

How it's made. Gathered by the New York State Mesonet network of ground stations and profilers during winter-storm deployments, provided here as browse-only PNG images.

How & where you'd use it. Was collected to study how snowbands form and to improve snowfall forecasting and remote-sensing interpretation.

Official description

The New York State Mesonet IMPACTS dataset is browse-only. It consists of temperature, wind, wind direction, mean sea level pressure, precipitation, and snow depth measurements, as well as profiler Doppler LiDAR and Microwave Radiometer (MWR) measurements from the New York State Mesonet network during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign, 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 advance prediction capabilities significantly. The Mesonet network consists of ground weather stations, LiDAR profilers, and microwave radiometer (MWR) profilers. These browse files are available from January 3, 2020, through March 2, 2023, in PNG format.
