Status

The IMPACTS campaign is a NASA-sponsored Earth Venture Suborbital-3 field campaign to study East Coast snowstorms over the course of three winters. The first two deployments took place in 2020 (see http://catalog.eol.ucar.edu/impacts_2020/ for the 2020 Field Catalog) and 2022 (see http://catalog.eol.ucar.edu/impacts_2022/ for the 2022 Field Catalog) and the third deployment occurred January-February 2023.

A total of 14 research flights were conducted during the 2023 deployment to sample winter storms spanning from the upper Midwest to the Northeast and Québec. Ten of those events involved successful coordination between the "satellite-simulating" ER-2, which contained radar, lidar, and microwave radiometer remote sensing instruments to sample the storm from above, and the "storm-penetrating" P-3 aircraft that housed microphysical instruments for in situ data collection and dropsondes to measure the thermodynamic profile when over the ocean. Ground assets covered an extensive area and included mobile radars, rawinsondes, and a network of meteorological and profiler stations to complement the ER-2 and P-3.

The data collection phase for the third and final deployment (2023) is complete and the links to the information on the operations and quick-look imagery can be found under the "Missions" and "Data" tabs above.
