The NASA Global Hydrology Resource Center (GHRC) DAAC now has the Lightning Imaging Sensor (LIS) on TRMM Science Data and the LIS on TRMM Backgrounds datasets available in netCDF/CF format, as well as the historical HDF-4 format. TRMM LIS was used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. The LIS Science Data consist of lightning and lightning density measurements and are used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day...GHRC News & Features

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Naval Research Laboratory (NRL) Near-Real Time Rain Rates IFloodS dataset. This data product was created for the GPM Iowa Flood Studies (IFloodS) field campaign from April 23, 2013 through June 30, 2013. The IFloodS field campaign was a ground measurement campaign that took place in eastern Iowa. The goals of the campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. This NRL real time rain rates data product was produced using the Probability Matching Method with rain gauge, Defense Meteorological Satellite Program (DMSP) F15 Special Sensor...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Goddard Profiling Algorithm (GPROF) 2014 IFloodS dataset. This dataset consists of precipitation data derived from microwave radiometers and sounders located on multiple satellites, including the Defense Meteorological Satellite Program (DMSP) F16-18, the Global Change Observation Mission – Water "Shizuku" (GCOM-W1), the European Space Agency's (ESA’s) Meteorological Operational satellite programme (MetOp) series, and NOAA's Polar Operational Environmental Satellites (POES) series. The data have been consistently... 08/22/2018 - 14:50
The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Reference Rainfall Data Product IFloodS dataset. This dataset contains hourly rainfall accumulation estimates over central and northeastern Iowa for the period of 1 May to 16 June, 2013. This product is created by combining ground-based radar estimates collected for the Iowa Flood Studies (IFloodS) campaign. The goals of the IFloodS campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the Hurricane and Severe Storm Sentinel (HS3) Statistical Hurricane Intensity Prediction Scheme (SHIPS) Intensity dataset. This dataset was obtained from March 18, 2014 through September 30, 2014 during the Hurricane and Severe Storm Sentinel (HS3) field campaign. Goals for the HS3 field campaign included assessing the relative roles of large-scale environment and storm-scale internal processes, addressing the controversial role of the Saharan Air Layer (SAL) in tropical storm formation and intensification, and the role of deep convection in the inner-core region of storms. The SHIPS model provides... 07/30/2018 - 09:44
The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX V2 dataset. This dataset was obtained by a dual-polarization and dual-frequency X-band mobile radar operated by the Center for Severe Weather Research (CSWR) during the Olympic Mountain Experiment (OLYMPEX) campaign. The DOW was deployed in the Chehalis Valley for the OLYMPEX field campaign with the goal of obtaining radar reflectivity and Doppler velocity observations in order to better understand the orographic enhancement of precipitation during frontal passages over mountain ranges. The DOW...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Composite Satellite Overpasses OLYMPEX datast. This dataset provides brightness temperature, precipitation, and total column water vapor estimates from multiple satellite overpasses including DMSP F16-19, GCOM-W1, GPM, MetOp, NOAA, and NPP for the OLYMPEX field campaign. The OLYMPEX field campaign took place between November, 2015, and January, 2016, with additional ground sampling continuing through February, on the Olympic Peninsula in the Pacific Northwest of the United States. This field campaign provides ground-based...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation TRMM Multi-satellite Precipitation Analysis (TMPA) IFloodS datasets. This dataset is a subset of the TMPA 3B42RT gridded precipitation real-time product selected for the time period of the GPM Ground Validation Iowa Flood Studies (IFloodS) held in Iowa during April 1, 2013 to June 30, 2013. The goals of IFloodS were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead... 06/22/2018 - 15:55
The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Global Flood Monitoring System (GFMS) Flood Maps IFloodS dataset. This dataset contains global flood estimates on a 0.25 degree spatial resolution every 3 hours, from March 26, 2013 through June 30, 2013. These data are provided in support of the Iowa Flood Studies (IFloodS) experiment conducted in eastern Iowa.
