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 is collected daily, and is available at 3-day, weekly and monthly intervals at a spatial resolution of 0.1. The geographic coverage is global, and the temporal coverage ranges from 2003-2016.

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 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.

Ocean color remote sensing provide routine, synoptic observations of the ocean surface at spatial and temporal resolutions not attainable by moored or ship-based platforms. Ocean color sensors measure the spectral distribution of reflected sunlight, which can be used to infer the contents of the water, including chlorophyll a concentrations, a proxy for phytoplankton biomass. Phytoplankton are the base of the marine food web and are critical regulators of key biogeochemical processes.

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 temperature measurements collected by means of the Geostationary Orbiting Environmental Satellite. The data is collected daily, and is available at 2-day intervals at a spatial resolution of 0.05 degrees. The geographic coverage extends for the Pacific region,and the temporal coverage ranges from 2001-present.

NOAA CoastWatch produces near real-time ocean color products, e.g., chlorophyll-a concentration and turbidity (reflectance), with data from NASA's GeoEye's Orbview-2 satellite (via contractual purchase). The data is collected by selected HRPT ground stations. The level 1A data consists of raw radiance counts from eight bands (six in visible and two in near infrared spectrum), calibration data, navigation data, instrument telemetry and selected spacecraft telemetry. Each level 2 satellite specific product has unique characteristics dependent on the sensor and the algorithm applied. While level 2 historic data is open to the public, level 1 data is restricted to users covered by SeaWiFS CoastWatch contract due to limitations associated with commercial data. The OrbView-2 spacecraft, which carried the SeaWiFS instrument, stopped communicating with Earth-based data stations in December 2010. After several months of attempts to revive the link, GeoEye, the company that operated the spacecraft, officially ended any further attempts at recovery.

The dataset contains satellite-derived sea-surface Photosynthetically Available Radiation (PAR) measurements collected by means of the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard the NASA Aqua satellite. The data is available at monthly (2002 - present) intervals at a spatial resolution of 0.05 degrees. The geographic coverage is global.
