    2015 Highlights - GHRC Accomplishments and Annual Report from 2015

  • "Profiles in Intensity"

    Earthdata's Agnieszka Gautier has written an article called "Profiles in intensity" describing how NASA's Hurricane and Severe Storm Sentinel (HS3) field campaign observations are being used to gain more insight into the intensity and convection structures of tropical storms. GHRC serves as an archive for HS3 data.

  • LANCE SWE imagery available in NASA Worldview

    Snow water equivalent (SWE) imagery is now available in NASA Worldview from the NASA Land Atmosphere Near real-time Capability for EOS (LANCE) Advanced Microwave Scanning Radiometer 2 (AMSR2) processing element. LANCE AMSR2 is a component of the AMSR Science Investigator-led Processing System (SIPS) at the GHRC DAAC. This NASA Worldview image shows snow in the Andes as seen from AMSR2 on August 25.

  • HyDRO

    We have improved HyDRO, our data discovery and access tool! The updated design improves the user experience in navigating search results to find all relevant dataset information, including metadata and documentation, browse imagery, inventory listing and download location.


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

Lightning science & LIS at GHRC


Two 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).

Hurricane science at GHRC


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 mision.

Storm induced hazards at GHRC

Storm-induced hazards

Global hydrological parameters such as sea surface temperature, atmospheric water vapor, wind direction, and atmospheric temperature are derived from various passive microwave instruments.

Have you ever wondered where the most lightning strikes occur on our planet? As it turns out, Lake Maracaibo in Venezuela earns top honors for the highest number of lightning strikes in a square kilometer, also known as lightning density. This phenomena is creatively explained in a new TED-Ed Lesson called “The most lightning-struck place on Earth” by Graeme Anderson. The lesson includes a ‘Dig Deeper’ section that explains where lightning strikes most. This section includes a description of the Optical Transient Detector (OTD) and the Lightning Imaging Sensor (LIS), two space-based sensors whose data is distributed at the Global Hydrology Resource Center (GHRC), one of NASA’s Distributed Active Archive Centers (DAAC). Check out the TED-Ed Lesson here:...

TRMM overpass over hurricane DeanGHRC DAAC has published the TRMM Cyclone Precipitation Feature (TCPF) Database - Level 1, providing TRMM-based tropical cyclone data in a common framework for hurricane science research.  This dataset aggregates observations from each of the TRMM instruments for each satellite orbit that was coincident with a tropical cyclone in any of the six TC-prone ocean basins. These swath data are co-located and subsetted to a 20-degree longitude by 20-degree latitude bounding box centered on the tropical storm, which is typically large enough to observe the various sizes of TCs and their immediate environments.  The TCPF Level 1 dataset was created by researchers at Florida...
