Minimize Climate Change Monitoring

The work of the United Nations Framework Convention on Climate Change (UNFCCC) and of the Intergovernmental Panel on Climate Change (IPCC) are supported by the Essential Climate Variables (ECV). All ECV are designed to be technically and economically viable for systematic observation. International exchanges are required to fulfil databases with present and historical observations. There are 50 ECVs currently defined.

Supporting this international effort, a substantial number of OLCI products include some ECVs (as shown in the following table).

ECV OLCI products
[Atmospheric Surface] Surface Radiation budget Photosynthetically available radiation
[Atmospheric Upper Air] Water Vapour Integrated water vapour column
[Atmospheric Composition] Aerosols properties Aerosol optical thickness
Aerosol Angstrom exponent
[Oceanic] Ocean Colour Water leaving reflectances
[Oceanic] Phytoplankton Algal pigment concentration
[Terrestrial] Albedo Rectified reflectances
[Terrestrial] Land cover Rectified reflectances
[Terrestrial] FAPAR OLCI global vegetation index
[Terrestrial] Over ground biomass OLCI terrestrial chlorophyll index
