  • LIS Very High Resolution Gridded Lightning Climatology Data Sets

    The LIS 0.1 Degree Very High Resolution Gridded Climatology (VHRcC) data collection is now available at GHRC DAAC.

  • Sensing Our Planet article highlighting GHRC DAAC data is currently featured on the NASA Earthdata Web site

  • New GHRC tool presented in ESIP webinar

    Manil Maskey presented GHRC’s new "Field Campaign Information Explorer" tool as part of the ESDIS webinar series. The webinar was well received by the audience and many additional features were suggested by potential users. View the demo on our YouTube channel.

  • GHRC DAAC UWG chair featured at NASA Earthdata

    GHRC DAAC's UWG Chair and AMSR2 PI Dr. Christian Kummerow was recently featured on the NASA Earthdata website in their segment, "Who uses NASA Earth science data?"

  • GHRC lightning data featured in TED-Ed Lightning talk

    Lake Maracaibo in Venezuela earns top honors for the highest number of lightning strikes in a square kilometer, also known as lightning density. Graeme Anderson references GHRC DAAC lightning data to creatively explain this phenomena in a new TED-Ed Lesson called “The most lightning-struck place on Earth.”


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 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).

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 mission.

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.

The GHRC DAAC has published dataset revisions for two merged satellite products from the DISCOVER MEaSUREs project:

·      RSS Monthly 1-deg Merged Wind Climatology netCDF V7R01

·      RSS Monthly 1-deg Microwave Total Precipitable Water netCDF V7R01

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...

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.

The LIS telescope can be seen at the lower right of the payload. Image by NASA's Kennedy Space Center.

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.
