Sentinel-3

The sea surface height team in NOAA’s Laboratory for Satellite Altimetry produces two experimental mesoscale eddy products:

• Multiparameter Eddy Significance Index (MESI)
• MUltiparameter NRT System for Tracking Eddies Retroactively (MUNSTER)

The NOAA Multi-Sensor Level-1 to Level-2 (MSL12) Ocean Color, science quality, multi-sensor 2 km global gap-filled analysis includes chlorophyll-a, K_d(490), and SPM products. These global gap-free data are generated using the data interpolating empirical orthogonal function (DINEOF) method (Liu and Wang, 2023). This product currently uses data from 3 instruments: the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite, VIIRS on the NOAA-20 satellite, plus the Ocean and Land Colour Instrument (OLCI) on the Sentinel 3A satellite from the Copernicus program of the European Union.

The NOAA Laboratory for Satellite Altimetry's (LSA) sea surface height team produces 0.25-degree longitude/latitude Level-3 sea level anomaly (SLA) daily datasets by applying optimal interpolation to along-track satellite observations over the global ocean from a constellation of radar altimeter missions. Theses grids are produced with near-real time (3-5 hour latency) data.  Geostrophic Currents are produced from the SLA and are included in the dataset.

OLCI Sentinel-3A and 3B regional coverage (US coasts of interest, a.k.a. "CONUS" but including Hawaii) Level-3 mapped daily composites of ocean color remote sensing reflectances (Rrs(λ), chlorophyll-a concentration and derived water quality related products including diffuse attenuation coefficient at 490 nm (Kd490),  normalized fluorescence line height (NLFH), and total suspended matter (TSM) from the EUMETSAT processing.

OLCI Sentinel-3A and 3B global coverage ocean color including visible remote sensing reflectances and derived parameters such as chlorophyll-a concentration and light attenuation coefficients.

OLCI true color products are generated from atmospheric corrected rho_s bands.  Data are available in mapped 300m regions in near real-time CoastWatch HDF format and are compatible with the CoastWatch Utilities.
