The dataset contains satellite-derived sea-surface temperature measurements collected by means of the Advanced Very High Resolution Radiometer - Global Area Coverage (AVHRR-GAC) sensor onboard the NOAA polar orbiting satellite constellation. The data consists of Pathfinder AVHRR SST data collected between 1985-2003; existing data thereafter consists of AVHRR-GAC data. Dataset contains weekly and monthly composites at a spatial resolution of 0.1 degrees. The geographic coverage extends for the entire globe.

The dataset contains blended satellite-derived sea-surface temperature measurements collected by means of the Geostationary Orbiting Environmental Satellites (GOES) and the Polar-orbiting Operational Environmental Satellites (POES). This global SST analysis provides a daily gap-free map of the foundation sea surface temperature. The data is collected daily, and is available at 2-day, weekly and monthly intervals at a spatial resolution of 0.05 degrees. The geographic coverage extends for the Pacific region,and the temporal coverage ranges from 2012-present.

The dataset is a reanalysis of historical data from the AVHRR (Advanced Very High Resolution Radiometer) sensor onboard the NOAA polar orbiting satellite constellation, that have been improved using extensive calibration, validation and other information to yield a consistent research quality time series for global climate studies. At 0.05 degrees per pixel (approximately 4 km/pixel), this dataset provides a global spatial coverage ranging from October 1981 - 2009. Our data holdings include descending passes (nighttime). The data is available as monthly and weekly composites, as well as a monthly climatology, at a spatial resolution of 0.05 degrees. The geographic coverage extends for the entire globe.

The dataset contains satellite-derived sea-surface height measurements collected by means of the TOPEX/Poseidon/ERS, JASON-1/Envisat, and Jason-2/Envisat satellite sensors. Reprocessed science quality monthly and weekly delayed data is collected when available from AVISO, Near-real time data is collected daily is available as weekly 7-day composites. All data is at a spatial resolution of approximately 0.25 degrees. The geographic coverage is global, and the temporal coverage ranges from 1993-present. The data is combined with a Niiler Climatology (Niiler et al., 1994) to obtain absolute sea surface heights. Geostrophic currents (u and v components) are mathematically derived, and available at a spatial resolution of 0.5º.

The dataset contains satellite-derived sea-surface salinity measurements collected by means of the Aquarius sensor onboard the NASA/CONAE SAC-D satellite. The data is available at weekly and monthly intervals at a spatial resolution of 1 degrees. The geographic coverage extends globally, and the temporal coverage ranges from 2011-2015.

The dataset contains satellite-derived sea-surface ocean color (chlorophyll-a) measurements collected by means of the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard the NASA Aqua satellite. The data is available at daily (2015 - present), weekly (2002 - present) and monthly (2002 - present) intervals at a spatial resolution of 0.05 degrees. The geographic coverage is global.

The dataset contains satellite-derived sea-surface ocean color (chlorophyll-a) measurements collected by means of the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor onboard the NASA Suomi National Polar-Orbiting Partnership (Suomi NPP) spacecraft. The data is available at weekly and monthly intervals at a spatial resolution of 0.05 degrees, from 2012 to present. The geographic coverage is global.

This archive covers two high resolution sea surface temperature (SST) analysis products developed using an optimum interpolation (OI) technique. The analyses have a spatial grid resolution of 0.25 degree and temporal resolution of 1 day. One product uses Advanced Very High Resolution Radiometer (AVHRR) infrared satellite data, while the other uses satellite data from both AVHRR and the Advanced Microwave Scanning Radiometer from NASA Earth Observing System (AMSR-E). Both products also use sea-ice data, in situ data from ships and buoys, and include a large-scale adjustment of satellite biases with respect to the in situ data. Two products are needed because of the increase in signal variance from AMSR-E due to its near all-weather coverage. For both products, the results show improved spatial and temporal resolution compared to heritage weekly 1.0 degree OISST analyses from the NWS NCEP. The AVHRR-only product uses Pathfinder AVHRR data, when available, from September 1981 through December 2005, and operational Navy AVHRR data for 2006 onwards. Pathfinder AVHRR was chosen because of good agreement with the in situ data. The combined AMSR-E and AVHRR product begins with the start of AMSR data in June 2002 and ends in October 2011, when the AMSR-E instrument ceased to function properly. In this second product, the primary AVHRR contribution is in regions near land where AMSR-E is not available. However, in cloud-free regions, use of both infrared and microwave instruments reduces systematic biases because the error characteristics are independent. For both products, in areas where sea ice is present, SST is estimated from sea ice fraction datasets from NASA GSFC before 2005 and then from NWS NCEP from 2005 onwards. Preliminary products are produced daily in near real-time (1-day latency) and may be updated in the first few days if critical input data become available after the initial production time. After two weeks, a complete or final product is generated with no additional changes expected. The preliminary products from near real-time data productions began in October 2008 for Version 2.0.
