The NASA Global Hydrology Resource Center (GHRC) DAAC added more data files to the GPM Ground Validation Validation Network (VN) dataset. This dataset contains reflectivity, hydrometeor identification, rain rate, correlation coefficient, and quality control variables and estimates. This data product was created using the Validation Network (VN), which performs a direct match-up of the Global Precipitation Mission (GPM)’s space-based Dual-frequency Precipitation Radar (DPR) and Microwave Imager (GMI) data with ground radar data from NOAA Weather Surveillance Radar-1988 Doppler (WSR-88D) radars. These data are...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the NOAA Soundings IMPACTS dataset. This dataset was collected from January 1, 2020 through February 29, 2020 during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. The goal of IMPACTS was to provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution, examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands, and improve snowfall remote sensing interpretation and modeling to...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the Mobile UIUC Soundings IMPACTS dataset. This dataset consists of atmospheric sounding data collected by rawinsondes launched during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. These data include vertical profiles of atmospheric temperature, relative humidity, pressure, wind speed, and wind direction. Specifically, these rawinsondes were provided by the University of Illinois at Urbana-Champaign (UIUC). IMPACTS was a three-year sequence of winter season deployments conducted to...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Lightning Instrument Package (LIP) IPHEx dataset. This dataset consists of electrical field measurements of lightning and navigation data collected by the Lightning Instrument Package (LIP) flown aboard a NASA ER-2 high-altitude aircraft during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina. The goal of IPHEx was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. These data files are...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation SEA FLUX ICE POP dataset. This dataset includes estimates of ocean surface latent and sensible heat fluxes, 10m wind speed, 10m air temperature, 10m air humidity, and skin sea surface temperature in support of the International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic Winter Games (ICE-POP) field campaign in South Korea. The two major objectives of ICE-POP were to study severe winter weather events in regions of complex terrain and improve the short-term forecasting of such events. These data...

The NASA Global Hydrology Resource Center (GHRC) DAAC published all five of the GPM Ground Validation C-Band Radar LPVEx datasets. These datasets consists of radar reflectivity data from the ground based dual-polarimetric C-Band Doppler radar network in Finland during the Global Precipitation Measurement (GPM) mission Light Precipitation Validation Experiment (LPVEx) field campaign. There are five separate datasets including data from the C-Band Ikaalinen (IKA) Radar, the C-Band Kerava (KER) Radar, the C-Band Korpo (KOR) Radar, the C-Band Kumpula (KUM) Radar, and the C-Band Vantaa (VAN) Radar. These radars provided...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GOES-R PLT Field Campaign Airborne Visible/Infrared Imaging Spectrometer Next Generation (AVIRIS-NG) dataset. This dataset consists of radiance, reflectance, water phase, and navigation data collected by the Airborne Visible/Infrared Imaging Spectrometer Next Generation (AVIRIS-NG) for the GOES-R Post Launch Test (PLT) field campaign. The GOES-R PLT field campaign took place from March to May of 2017 in support of post-launch L1B and L2+ product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning...

The NASA GHRC DAAC is currently prepping for the IMPACTS data publication to ensure a quick turn-around on publishing after receiving the full dataset. These prep efforts include sending out a Questionnaire Form to the PI for each dataset, which is an extensive form describing the data to help with documentation. Also, we have requested a sample file for each data format. We will use the information provided to create a user guide and metadata generation code for each dataset. So far, we have received sample data for 48 datasets and Questionnaire Forms for 52 datasets. Also, we have completed draft user guides for 38 datasets...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GOES-R PLT Mission Reports dataset. This dataset consists of various reports filed by the scientists during the GOES-R Post Launch Test (PLT) field campaign including flight reports, weather forecasts, mission scientist reports, and plan-of-day reports. The campaign took place from March to May of 2017 in support of post-launch L1B and L2+ product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). The GOES-R PLT Mission Reports dataset contains reports...
