The Terrestrial Information Systems Laboratory and Global Change Data Center Merge to Form New NASA Office

09.01.2022
In August 2022, the Terrestrial Information Systems Laboratory and the Global Change Data Center merged to form a new office in the Earth Science division at NASA Goddard Space Flight Center. While the new office maintains the name, “Terrestrial Information Systems Laboratory,” the merger presents more opportunities to collaborate, supporting Earth science research and innovation across different science disciplines (atmosphere, biosphere, and hydrosphere science).

The new office produces, archives, and distributes important atmospheric data products from NASA’s Goddard Space Flight Center in Greenbelt, MD and is home to three data centers, the Level-1 and Atmosphere Archive and Distribution System (LAADS) Distributed Active Archive Center (DAAC), the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) and the Ocean Biology DAAC (OB.DAAC). These data centers are three of twelve NASA Science Mission Directorate (SMD) data centers that provide Earth science data, information, and services to research scientists, applications scientists, applications users, and students. LAADS DAAC and GES DISC primarily provide atmospheric data, with LAADS DAAC providing data focused on clouds and aerosols, while GES DISC primarily distributing atmospheric composition, precipitation, and climate variability data. The Ocean Biology DAAC (OB.DAAC) processes ocean biology data from the Moderate Imaging Spectroradiometer (MODIS), Visible Infrared Radiometer Suite (VIIRS), Ozone Monitoring Instrument (OMI), Ozone Mapping Profiler Suite (OMPS), and Global Precipitation Measurement (GPM). Additionally, the new office also supports the Precipitation Processing System (PPS) which processes satellite radar data to measure precipitation globally.

The new office oversees programs including the Fire Information for Resource Management System (FIRMS), MODIS Adaptive Processing System (MODAPS), Ozone Monitoring Instrument Data Processing System (OMIDAPS), and the Land, Atmosphere Near-real-time Capability for EOS (LANCE). These programs provide essential data for monitoring natural hazards around the world, helping people prepare and respond to natural hazards, like fires, floods, and food security, using satellite data to aid in decision making.

Overview

The Global Change Data Center (GCDC) is an office in the Earth Sciences Division located at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The GCDC:

  • provides multi-mission data and information systems to generate and distribute products from Earth observing satellites;
  • supports collaboration to promote the interchange and reuse of technology, data and services among developers and users;
  • conducts research in algorithm development, product validation, data discovery and science applications; and
  • leverages staff expertise in system management, system development, standards and program support on behalf of external organizations.
