Featured Missions & Projects - Global Change Data Center (610.2)
The Earth Science Data Systems Working Groups were chartered as a part of the Strategic Evolution of Earth Science Enterprise Data Systems (SEEDS) formulation team report. The purpose of SEEDS was to establish a framework for distributed data management to maximize availability and utility of Earth Science Enterprise products, leverage community expertise, ideas, and capabilities; and improve overall effectiveness of ESE-funded systems and services. The Working Groups were initially a part of the Research, Education and Applications Solutions Network (REASoN) projects, and later were included in the Advancing Collaborative Connections for Earth System Science (ACCESS) program and the Making Earth Science Data Records for Use in Research Environments (MEaSUREs) program. The web site provides basic information about the awards and provides applications to track their progress and report metrics.
GCMD enables users to locate and obtain access to Earth science data sets and services relevant to global change and Earth science research. The GCMD database holds more than 25,000 descriptions of Earth science data sets and services covering all aspects of Earth and environmental sciences. One can use the search box or select from the available keywords to search for data and services. We encourage your participation in writing and maintaining the information in our databases. You will find authoring tools to assist you. In addition, subscription services are available to notify you of new entries. The Committee on Earth Observation Satellites (CEOS) International Directory Network (IDN) Interoperability Forum is available to discuss content and database issues.
We are one of eight NASA Science Mission Directorate (SMD) DAACs that offer Earth science data, information, and services to research scientists, applications scientists, applications users, and students. The GES DISC is the home (archive) of Precipitation, Atmospheric Chemistry and Dynamics, and information, as well as data and information from other related disciplines. The GES DISC is located at Goddard Space Flight Center, in Greenbelt, Maryland.
NASA's Ocean Biology Processing Group supports the collection, processing, calibration, validation, archive and distribution of ocean-related products from a number of missions which are supported within the framework and facilities of the current NASA Ocean Data Processing System (ODPS) which has been successfully supporting operational, satellite-based remote-sensing missions since 1996. The group's capabilities continue to evolve and expand to meet the demands and challenges of future missions.
Missions, data sets and activities currently supported or in development include:
SeaWiFS : 1997 - present, MODIS (Terra and Aqua) : 2000 - present, MERIS (US Coastal Waters) Feb 2009 - present , CZCS / Nimbus-7 : 1978 - 1986, OCTS / ADEOS-I : 1996 - 1997, Glory data system prototype : 2010 launch, Aquarius / SAC-D : Late 2010 launch, VIIRS / NPP : January 2011 launch, Community Processing & Analysis Software SeaDAS (1991- present)
The Tropical Rainfall Measuring Mission (TRMM) has its own unique Precipitation Processing System (PPS) to process information from the satellite. PPS analyzes TRMM rainfall data as well as data from other Precipitation based missions and also provides validation from nearly a dozen TRMM ground radar sites.
