GHRC News

The NASA Global Hydrology Resource Center (GHRC) DAAC published the P-3 Meteorological and Navigation Data IMPACTS dataset. This dataset is a subset of airborne measurements that include GPS positioning and trajectory data, aircraft orientation, and atmospheric state measurements of temperature, pressure, water vapor, and horizontal winds. These measurements were taken from the NASA P-3 aircraft during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign. Funded by NASA’s Earth Venture program, IMPACTS is the first comprehensive study of East Coast snowstorms in 30 years. The campaign 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 significantly advance prediction capabilities. Data are available in ASCII-ict format from  January 12, 2020 through February 26, 2020.
The NASA Global Hydrology Resource Center (GHRC) DAAC published the Turbulent Air Motion Measurement System (TAMMS) IMPACTS dataset. This dataset consists of wind speed, wind direction, and cross wind speed measurements from the TAMMS instrument onboard the NASA P-3 aircraft during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic Coast (2020-2022). The campaign 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 significantly advance prediction capabilities. The files are available from  January 18, 2020 through February 26, 2020 in ASCII-ict format. It should be noted that the NASA P-3 aircraft did not operate each day of the campaign, therefore TAMMS data are only available for aircraft flight days.
The NASA Global Hydrology Resource Center (GHRC) DAAC published the NASA ER-2 Navigation Data IMPACTS dataset. This dataset contains information recorded by the on-board navigation and data collection systems of the NASA ER-2 high-altitude research aircraft. In addition to typical navigation data (e.g., date, time, latitude/longitude, and altitude) it also contains outside meteorological parameters such as wind speed, wind direction, and temperature. These data were collected 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 significantly advance prediction capabilities. The IMPACTS navigation dataset files are available from January 15 through March 2, 2020 in ASCII-ict format. It should be noted that there is one file per flight.  Since flights did not occur each day of the campaign, data are only available on flight days.
The NASA Global Hydrology Resource Center (GHRC) DAAC published the SeaFlux Data Products. This dataset consists of estimates of ocean surface latent and sensible heat fluxes, 2m and 10m wind speed, 2m and 10m air temperature, 2m and 10m air humidity, and skin sea surface temperature. This data product was created by using the SeaFlux V3 model. These data are available globally from January 1, 1988 through December 31, 2018 in netCDF-4 format.
