MSI Sentinel-2 Imagery

MSI Sentinel-2 high spatial resolution imagery and data from Copernicus are served from CoastWatch for coastal US regions in near real time as the data become available. JPEG and TIF images as well as zipped Level 1C data are available.

True Color OLCI Sentinel-3A/B

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.

The Sentinels are a suite of satellite missions developed to serve the operational needs of the European Copernicus program for Earth observations. NOAA CoastWatch/OceanWatch provides Sentinel data to US users through official arrangements with ESA, EUMETSAT and the European Commission.

Sentinel-3 is a multi-instrument mission to measure sea- and land-surface temperature, ocean and land color and sea-surface topography. Sentinel-3A was launched on 16 February 2016. Sentinel 3B was launched successfully on 25 April 2018 with the same instruments.

The Ocean and Land Colour Instrument (OLCI) is based on heritage from Envisat’s Medium Resolution Imaging Spectrometer (MERIS to measure visible and thermal infrared radiances, i.e., true color, ocean color and derived parameters such as chlorophyll, total suspended matter (TSM), diffuse attenuation coefficient at 490 nm (Kd(490)), absorption at 443 nm (a(443). OLCI has 21 bands at wavelengths from 400 nm to 1020 nm (400, 412, 442, 490, 510, 560, 620, 665, 674, 681, 709, 754, 779, 865, 885, 1024 nm), a spatial resolution of 300 m and a swath width of 1270 km.

OLCI Level 1b (e.g., true color) and ocean color Level 2 data (e.g., radiances, chlorophyll, etc.) are generated by EUMETSAT (https://www.eumetsat.int/sentinel-3) and served by CoastWatch. CoastWatch also generates L3 mapped products for US Coastal regions.

True Color VIIRS S-NPP/NOAA-20

True color bands are provided from VIIRS on both S-NPP and NOAA-20 VIIRS spacecraft. These top-of-atmosphere products are generated from the emissive bands (M-bands) for wavelengths corresponding to Red, Green, and Blue and are provided in CoastWatch HDF and PNG daily composite mapped regions
