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.
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.
Testing at NASA’s Kennedy Space Center (KSC) has been completed for the DoD STP-H5 (Space Test Program-Houston 5) package, which contains the International Space Station Lighting Imaging Sensor (ISS-LIS). STP-H5 has been put in “dwell” until time to integrate on the SpaceX spacecraft - set to launch August 1 for a 2-4 year or longer mission. ISS-LIS is a sister instrument to the LIS on NASA’s TRMM satellite. GHRC DAAC will provide product generation, archive and data distribution for ISS-LIS data.
The GHRC DAAC has extended the “Hurricane and Severe Storm Sentinel (HS3) Global Hawk Advanced Vertical Atmospheric Profiling System (AVAPS) Dropsonde System” dataset, with the addition of ASCII data files to complement the existing netCDF data. With the addition of these files, the entire AVAPS dropsonde dataset for HS3 is now available in both netCDF-4, the standard used for all HS3 data at GHRC, as well as the NCAR Earth Observing Laboratory’s “EOL” ASCII file format convention for sounding data, commonly used in the science community.
