Polymer<\/h1><\/div>

Polymer1<\/sup> recovers the radiance scattered and absorbed by the oceanic and inland waters from the signal measured by satellite sensors in the visible spectrum. One of the strengths of this algorithm is the possibility to recover the water colour in presence of sun glint<\/strong>. This leads to a much-improved spatial coverage compared to other algorithms.<\/p>\n<\/div>

Polymer is applied to multiple polar-orbiting sensors from ESA (Envisat\/MERIS, Sentinel-3\/OLCI, Sentinel-2\/MSI, \u2026) and NASA (SeaStar\/SeaWiFS, Aqua\/MODIS, Suomi\/VIIRS) and to hyperspectral sensors (PRISMA, HICO). It is used in several Earth Observation projects, by many research institutes, for water quality<\/a> applications.<\/p>\n

Polymer version 5 is currently in development and will be released soon.<\/p>\n

Polymer terms and conditions of use are available here<\/a>.<\/p>\n

Operational services based on Polymer<\/strong><\/h3><\/div><\/div><\/div>

Polymer is recognized for its high performance and reliability. That’s why it is implemented in the operational processing chains of the Copernicus Marine Service, <\/strong>of the Copernicus Climate Change Service <\/strong>and in the Copernicus Land Monitoring Service <\/strong>to generate near-real-time and\/or archive products.<\/p>\n<\/div><\/div><\/div>
