The Distributed Active Archive Centers (DAACs) are part of NASA's Earth Observing System Data and Information System (EOSDIS). Each of the twelve data centers serves one or more specific Earth science disciplines and provides its user community with data products, data information, user services, and tools unique to its particular science.
The Global Hydrometeorology Resource Center (GHRC) DAAC is supported by NASA and is managed jointly by the Marshall Space Flight Center's Earth Science Office and The University of Alabama in Huntsville's Information Technology & Systems Center. The GHRC DAAC’s missions are 1) to serve as NASA’s Earth science data stewards for scientific, educational, commercial and governmental communities, with a focus on data for the global hydrologic cycle including precipitation, lightning and severe weather and 2) to provide knowledge augmentation services encompassing tools, infrastructure, user support, and expertise to our stakeholders.
The GHRC User Services Office staff is the point of contact for all questions, comments, and inquiries about the GHRC web site and all GHRC services. Contact us by phone or e-mail:

GHRC follows the definitions of the EOSDIS Data Panel report for data management and with the Committee on Data Management, Archiving and Computing (CODMAC) definitions. An overview of data set processing levels may be found here: https://ghrc.nsstc.nasa.gov/home/proc_level.
Various data collections at the GHRC DAAC may be handled with different levels of service (LoS). For some aspects of data services, such as ingest method, LoS corresponds to characteristics of the data. For other aspects of data services, LoS will depend on overall data handling priority assigned to the general categories of GHRC data holdings based on our processing policies. An overview of GHRC data set processing levels may be found here: https://ghrc.nsstc.nasa.gov/home/ghrc-docs/levels-of-service.
GHRC DAAC data are free of charge.

The Land Atmosphere Near real-time Capability for EOS (LANCE) elements provide near real-time (NRT) EOS data products within 3 hours of satellite observation with high availability. LANCE data and imagery are used for monitoring and analyzing a wide range of natural and man-made phenomena. The NASA LANCE AMSR2 element is located at the GHRC DAAC:

The GHRC Search Portal is a data search tool that can help you locate and obtain GHRC data. It was made to be user friendly, concise, and easy to use. More information about the GHRC Search Portal can be found on the GHRC Search Portal Help Page.
The Lightning Imaging Sensor (LIS) is a small, highly sophisticated instrument that detects and locates lightning using a combination of optical and electrical components. LIS can detect total lightning (cloud-to- cloud, cloud-to-ground, and intra-cloud flashes) from a space-based platform. LIS operated on the Tropical Rainfall Measuring Mission (TRMM) from 1997 to 2015, and will be launched on the International Space Station (ISS) in 2017. More information about LIS is available at https://ghrc.nsstc.nasa.gov/home/micro-articles/earth-observations-lightning- imaging-sensor.
A Field Campaign is an observational study planned for a specific location and a defined time period during which measurements are conducted from airborne platforms and/or ground sites to study physical and chemical processes in the atmosphere. More information about Field Campaigns is available at https://ghrc.nsstc.nasa.gov/home/field-campaigns.
