GHRC News

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.

The NASA Global Hydrology Resource Center (GHRC) DAAC published the NCAR Particle Probes IMPACTS dataset. This dataset consists of data collected from five instruments on the NASA P-3 aircraft, the SPEC Hawkeye Cloud Particle Imager (CPI) and Fast Cloud Droplet Probe (FastCDP), the SPEC Two-Dimensional Stereo probe (2D-S), and two SPEC High Volume Precipitation Spectrometers (HVPS3).  The 2D-S and HVPS3 are two-dimensional optical array probes which record images of particles that travel through their sampling area. The recorded images are then analyzed to produce particle size distributions from 20 microns to 3 centimeters in diameter.  The FastCDP is a forward scattering instrument designed to measure the size and concentration of cloud droplets between 2 and 50 microns in diameter.  The CPI is a high-resolution imager with a 256-level color depth.  No particle concentration estimates have been attempted with the CPI. 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. Data files are available in netCDF-4 format, as well as browse imagery available in PNG format, from January 18, 2020 through February 26, 2020.
The NASA Global Hydrology Resource Center (GHRC) DAAC published the Cloud Physics LiDAR (CPL) IMPACTS dataset. This dataset consists of backscatter coefficient, lidar depolarization ratio, layer top/base height, layer type, particulate extinction coefficient, ice water content, and layer/cumulative optical depth data collected from the Cloud Physics LiDAR (CPL) onboard the NASA ER-2 high-altitude research aircraft in support of 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 dataset files are available in HDF-5 format from January 15 through March 2, 2020. It should be noted that the ER-2 aircraft did not operate each day of the campaign, therefore, data are only available on flight days.
