The mission of the GHRC DAAC is to provide a comprehensive active archive of both data and knowledge augmentation services with a focus on hazardous weather, its governing dynamical and physical processes, and associated applications. Within this broad mandate, GHRC will focus on lightning, tropical cyclones and storm-induced hazards through integrated collections of satellite, airborne, and in-situ data sets.
Science Focus Areas
Two NASA space-based instruments have collected lightning data worldwide for the past fifteen years; first the Optical Transient Detector (OTD) and later the Lightning Imaging Sensor (LIS).
GHRC is the archive and distribution center for data collected during NASA's Hurricane Science Research Program (HSRP) field campaigns, as well as the recent HS3 Earth Venture mission.
Global hydrological parameters such as sea surface temperature, atmospheric water vapor, wind direction, and atmospheric temperature are derived from various passive microwave instruments.
GHRC DAAC science team member and Earth System Science graduate student Amanda Weigel was awarded the Raskin Scholarship (http://esipfed.org/raskinscholarship), which is offered by the Federation of Earth Science Information Partners (ESIP) to cover expenses for a graduate student to attend and present at the ESIP summer meeting. Her research focuses on the geospatial modeling of natural hazards and land-atmosphere interactions in tornado genesis, which has been funded through the NASA DEVELOP National Program, the UAH Master’s Competitive Internship Program and the UAH Industry/University Cooperative Graduate Student Research Program.
The GHRC DAAC published the GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEX dataset (doi: 10.5067/GPMGV/IPHEX/D3R/DATA101). This data was collected from May 3, 2014 to June 15, 2014 during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina. The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (...
The GHRC DAAC has published dataset revisions for two merged satellite products from the DISCOVER MEaSUREs project:
These data sets contain one-degree grids of monthly means, a 20-year climatology file, and a trend file containing the cumulative global trend map on a one degree grid and the time-latitude plot. They...
The Global Hydrology Resource Center (GHRC) DAAC published NASA Global Precipitation Measurement Mission Ground Validation model datasets from two GPM GV field campaigns:
As part of its work with the Big Earth Data Initiative, the GHRC DAAC now offers its AMSU/MSU temperature anomalies datasets in netCDF, in addition to the native format supplied by the data provider. These datasets are now accessible via OPeNDAP services.
