The NASA Global Hydrology Resource Center (GHRC) DAAC published the GOES-R Post Launch Test (PLT) Fly’s Eye GLM Simulator (FEGS) dataset. This dataset consists of lightning flash, lightning pulse, and radiance data collected by the FEGS flown aboard a NASA ER-2 high-altitude aircraft during the GOES-R Post Launch Test (PLT) airborne science field campaign. The GOES-R PLT airborne science field campaign took place between March 21 and May 17, 2017 in support of the post-launch product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). The FEGS instrument was...

The NASA Global Hydrology Resource Center (GHRC) DAAC published 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 available from...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Met One Rain Gauge Pairs Wallops Flight Facility (WFF) dataset. This dataset contains rain rate data from 4 rain gauge networks located in Virginia and Maryland near the Wallops Flight Facility (WFF): Nassawadox, Pocomoke, HalfDeg and Wallops Flight Facility (WFF) Assorted Gauges. These data were collected in support of the Global Precipitation Mission (GPM) Ground Validation (GV) campaign. The Met One Rain Gauge Pairs are tipping bucket precipitation gauges which collect precipitation amounts and calculate rain rates. The...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Multi-Radar/Multi-Sensor (MRMS) Precipitation Reanalysis for Satellite Validation Product dataset. This dataset contains precipitation rate and type estimates, quality control products, and precipitation corrective factors products. These data products were created using the NOAA MRMS System which ingests Weather Surveillance Radar 88 Doppler (WSR-88D) radar data, Rapid Update Cycle (RAP) model analysis fields, and gauge data. It should be noted that these data products are not standard MRMS. Significant post-processing is...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Autonomous Parsivel Unit (APU) Wallops Flight Facility (WFF) dataset. This dataset consists of precipitation data including precipitation amount, precipitation rate, reflectivity in Rayleigh regime, liquid water content, drop diameter, and drop concentration obtained from six Autonomous Parsivel Units (APUs) positioned at the Wallops Flight Facility (WFF) in support of the Global Precipitation Mission (GPM). The APU is an optical laser-disdrometer based on single particle extinction that measures particle size and fall...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the Hurricane and Severe Storm Sentinel (HS3) Global Modeling and Assimilation Office (GMAO) Dust Aerosol Optical Thickness Imagery dataset. This dataset consists of browse only imagery showing dust aerosol optical thickness and wind speed/direction from the Goddard Earth Observing System Model, version 5 (GEOS-5). These data are used to see how the Saharan Air Layer (SAL) affects hurricane development during the Hurricane and Severe Storm Sentinel (HS3) field campaign. Goals for the HS3 field campaign included assessing the relative roles...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the AMSU/MSU Day/Month Temperature Anomalies and Annual Cycle V6 datasets. These datasets consist of temperature anomalies and annual cycle temperatures derived from the Microwave Sounding Unit (MSU) and the Advanced Microwave Sounding Unit-A (AMSU-A) radiance data since January 1978. All products are derived for four bulk layers of the atmosphere: the lower stratosphere, tropopause, mid-troposphere, and lower troposphere. The datasets begin on January 1, 1978, and are still currently ongoing. The data are available in netCDF-4 and ASCII formats. In addition, the AMSU/MSU Day/Month Temperature Anomalies and Annual Cycle V5 datasets have been retired. Please now refer to the V6 datasets for the most up-to-date and...
