Upon formal release by EUMETSAT, OLCI Level 2 ocean color data products also will be available through CoastWatch/OceanWatch. In accordance with a Technical Arrangement with EUMETSAT, NOAA is the primary provider of Sentinel-3 marine data for the US. OLCI data can be accessed through CoastWatch/OceanWatch using the granule selector tool.
From this tool, users can select granules of regions and dates of interest and view and download PNG true color images or download data files in either EUMETSATTAR or CoastWatch HDF data formats. Multiple files can be downloaded at one time by selecting each granule of interest and clicking the "+" to add file names to the data cart, then automatically generate a list of those files to use in a download script (e.g., wget, etc.).
