    The NOAA Atlantic Real-Time Ocean Forecast System (RTOFS) dataset comprises output fields from the daily operational RTOFS model runs conducted at the National Centers for Atmospheric Prediction. Each model run produces a series of gridded fields containing results of model computations for ocean temperature, salinity, currents, sea-surface height, and possibly other properties. The fields are encoded in the standard GRIdded Binary (GRIB) file format. NODC compiles a series of files into monthly accessions to facilitate archival storage and public access. Two different sets of output fields are included: 1) daily 3-dimensional fields reported on the model's native hybrid (isopycnal plus z-level) vertical coordinates (note: prior to June 6, 2007, these fields are interpolated to z-levels); and 2) hourly fields reported for the surface level only. Each daily model run produces a 24-hr hindcast as well as forecasts out to 120 hours.

    The accession contains satellite spatially-averaged Sea Surface Temperature data collected as part of Tropical Ocean Global Atmosphere (TOGA). The data was collected between January 1, 1992 and December 31, 1993 by Colorado Center for Astrodynamics Research, University of Colorado, Boulder, CO. 52 files of data were submitted by Dr. William Emery to NODC.

    The Satellite Sea Surface Temperature and other data in this accession was collected from NOAA AVHRR satellite in TOGA Area - Pacific (30 N to 30 S) as part of Tropical Ocean Global Atmosphere and Coupled Ocean-Atmosphere Response Experiment. The data was collected between January 1, 1992 and December 21, 1993 by Colorado Center for Astrodynamics Research, University of Colorado. Two files of AVHRR SST data were submitted by Dr. William Emery to NODC via FTP.

    The Generalized Digital Environmental Model (GDEM) is a four-dimensional (4-D) steady-state digital model of ocean temperature and salinity. The model consists of gridded sets of coefficients with a grid spacing of 30 arcminutes (') in space and 3, 6, or 12 months in time with the exception of the coefficient describing sea-surface temperature, which is gridded at a 1-month interval. Utilizing these coefficient sets with the appropriate one-dimensional linear or cubic spline interpolation in time, vertical profiles of historical temperature and salinity extending from the surface to the bottom may be computed for a desired time for all locations where the water depth is at least 100 m. The VGDEM is a 4-D model of ocean temperature variability. A number of accumulations and parameters exists for each grid cell such that statistics on the observations can be derived; statistics based on comparing the observations with GDEM can be computed; and statistics computed for the mixed-layer depth and the in-layer and below-layer gradients. The percent of the observations suggesting half-channel is also available. Variability models will be constructed only in the ocean basins where data density permits. Therefore, models for the South Atlantic, South Pacific, and Arctic Oceans will not be developed at this time. The original source of data for the construction of these climatological models is the Master Oceanographic Observation Data Set (MOODS), which contains over 4.5-million profiles of temperature/salinity dating back to 1920. This data base is maintained by NAVOCEANO and is continually updated.

    This archival package contains an operational Satellite Ocean Heat Content Suite (SOHCS) product generated by NOAA National Environmental Satellite, Data, and Information Service (NESDIS). The operational algorithm implemented was developed at the University of Miami/Rosenstiel School of Marine and Atmospheric Science (RSMAS). The SOHCS product measures the integrated vertical temperature from the sea surface to the depth of the 26°C isotherm. The Algorithm uses a reduced gravity model to estimate the 20 degree isotherm depth based on objectively analyzed blended sea surface height anomaly fields from operational altimeters (Satellite with ARgos and ALtiKa (SARAL), Jason-1, Jason-2 and Cryosat-2) and Geo-Polar blended SST analyses. The data consists of seven parameters including sea surface height anomaly and its mapping error, depth of the 20° and 26° Celsius isotherm, mixed layer depth, ocean heat content and sea surface temperature. The grid spacing of the data in both latitude and longitude is 0.25°.

    This accession contains one month of geodetic data records (GDRs) from the GEOSAT Exact Repeat Mission (ERM) for the time period of October 22, 1988 to November 24, 1988. Parameters include: time, orbit, latitude/longitude, and sea surface height. Corrections to the data include: sea level, wind and wave data, tides, dry and wet troposphere, ionosphere, height bias, altimeter crossover differences, altimeter sea surface measurement, and spacecraft orientation. These data were submitted by the U.S. Navy via National Oceanic Service. The US Navy Geosat (Geodetic Satellite) radar altimeter mission lasted for nearly 5 years (March 1985 to January 1990) and collected approximately 750 million measurements of sea level, wave height, and wind speed over the global oceans. During the Geodetic Mission (March 1985 to September 1986), the satellite did not repeat its ground track for the duration of the mission. The orbit of the satellite was changed in early October 1986 to begin the Exact Repeat Mission (ERM) which lasted from November 1986 until the satellite quit functioning in January 1990. During the ERM, the satellite repeated its ground track every 17 days. Data were initially processed by the Johns Hopkins University Applied Physics Laboratory in Laurel, MD in coordination with the NOAA/NOS Satellite Altimeter Group. Data products were transferred to the NOAA National ceanographic Data Center (NODC) for distribution. Data products are archived at the NODC.
