IMPACTS Data Collection

Explore the data collection for NASA's Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign.

The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS), funded by NASA’s Earth Venture program, was the first comprehensive study of East Coast snowstorms in 30 years. IMPACTS flew a complementary suite of remote sensing and in-situ instruments for three 6-week deployments (2020-2022) on NASA’s ER-2 high-altitude aircraft and P-3 cloud-sampling aircraft. 

The first deployment began on January 17, 2020, and ended on March 1, 2020. IMPACTS sampled U.S. East Coast winter storms using advanced radar, LiDAR, and microwave radiometer remote sensing instruments on the ER-2, and state-of-the-art microphysics probes and dropsonde capabilities on the P-3, augmented by ground-based radar and rawinsonde data, multiple NASA and NOAA satellites (including GPM, GOES-16, and other polar orbiting satellite systems), and computer simulations.
