The Global Hydrology Resource Center (GHRC) provides both historical and current Earth science data, information, and products from satellite, airborne, and surface-based instruments. The GHRC acquires basic data streams and produces derived products from many instruments spread across a variety of instrument platforms. The GHRC is supported by NASA and is the data management and user services arm of the Global Hydrology & Climate Center (GHCC) in Huntsville, Alabama.

Search and Access Data
Test the waters of our new data pool — on-line access to half a terabyte of passive microwave data. Interactive search, subsetting, FTP access and OPeNDAP available. Go for a swim at http://datapool.nsstc.nasa.gov/.
Lightning Imaging Sensor
Space-based lightning observations are obtained from the Lightning Imaging Sensor (LIS), the Optical Transient Detector (OTD, 1995-2000), and surface validation networks in the continental U.S. and Brazil. Global hydrological parameters such as sea surface temperature, atmospheric water vapor, wind direction, and atmospheric temperature, are derived from several passive microwave instruments aboard TRMM, NOAA-15, NOAA-16, and SSM/I satellites.
Hurricane Studies
The Convection and Moisture Experiment (CAMEX) archive provides data from the 1998 CAMEX-3 field experiment and the 2001 CAMEX-4 field experiment in Jacksonville Florida. Data is also available from the Tropical Cloud Systems and Processes (TCSP) mission in 2005 in Costa Rica and NASA African Monsoon Multidisciplinary Analyses (NAMMA) mission in 2006 in the Cape Verde Islands. These experiments produced high-resolution spatial and temporal information of hurricane structure, dynamics, and motion.
The DISCOVER Project
The primary objective of the Distributed Information Services for Climate and Ocean Products and Visualizations for Earth Research (DISCOVER) Project is to provide highly accurate, long-term ocean and climate products suitable for the most demanding Earth research applications via easy-to-use display and data access tools.
Most data are publicly available, although some restrictions apply on the distribution of commercially obtained data. All data and products are currently free of charge.
