Earthdata Forum provides a central, online location where data users can interact with subject matter experts from NASA’s Distributed Active Archive Centers (DAACs) to discuss data applications and research needs, and get answers to specific questions about accessing, viewing, and manipulating NASA Earth observation data. Current Forum participants include NASA's Atmospheric Science Data Center (ASDC), Crustal Dynamics Data Information System (CDDIS), Global Hydrology Resource Center DAAC (GHRC DAAC), Goddard Earth Sciences Data and Information Services Center (GES DISC), Land Processes DAAC (LP DAAC), Level-1 and Atmosphere Archive and Distribution System DAAC (LAADS DAAC), and now OB.DAAC.
OB.DAAC data holdings include a mixture of historical and current ocean color missions, including the joint NASA/NOAA missions: the Joint Polar Satellite System (JPSS-1 a.k.a. NOAA-20, 2017-present) and Suomi-National Polar orbiting Partnership (Suomi NPP, 2011–present); the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra (1999–present) and Aqua (2002–present) satellites; the SeaWiFS instrument aboard the SeaStar satellite (1997–2010), the Coastal Zone Color Scanner (CZCS) instrument aboard the Nimbus-7 satellite (1978–1987); the MEdium Resolution Imaging Spectrometer (MERIS) aboard the European Space Agency's Envisat satellite (2002–2012); and the Ocean Colour Monitor-2 (OCM) aboard the Indian Space Research Organisation's Oceansat-2 satellite (2009–present).
Data from these missions are available through OB.DAAC’s Ocean Color website, which allows users to search the DAAC’s ocean color data archive, filter by spatial and temporal parameters and time periods, and order data from single files to the entire mission. OB.DAAC also offers a full suite of services and tools, including sensor calibration and characterization and algorithm development; the SeaWiFS Data Analysis System (SeaDAS), a comprehensive software package for the processing, display, analysis, and quality control of remote-sensing Earth data; and the SeaWiFS Bio-optical Archive and Storage System (SeaBASS), a public repository of in situ oceanographic and atmospheric data, to support their routine algorithm development and satellite data product validation activities.
Established at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in 2004, OB.DAAC is managed by NASA's Ocean Biology Processing Group (OBPG). OB.DAAC is responsible for archiving satellite ocean biology data produced or collected under NASA’s Earth Observing System Data and Information System (EOSDIS). OB.DAAC's holdings include a mixture of historical- and current-mission data, as well as data from both NASA and partner space organizations.
