Research project: Expert support Lab : The Sentinel-3 Mission Performance Center

Currently Active: 
Yes

We lead the validation of Copernicus Sentinel 3 OLCI land products: the OLCI Global Vegetation Index (OGVI) and the OLCI Terrestrial Chlorophyll Index (OTCI) to ensure they meet the user requirements.

Funding Source: European Space AgencyAwarded amount: £247,165.00

End Date: 30/09/21

The Copernicus Sentinel-3 satellite systematically observes Earth's surfaces and the atmosphere to monitor and large-scale global dynamics. Over land, this innovative mission provides a bigger picture by monitoring wildfires, mapping the characteristics of land surfaces, providing indices of vegetation state and measuring the height of rivers and lakes. The Sentinel-3 Mission Performance Center (S3MPC) is responsible for monitoring the performance of all these sensors, both in terms of internal calibration values and in the quality of the derived geophysical variables. University Of Southampton is involved in quality assurance of the two land products: he OLCI Global Vegetation Index (OGVI), providing the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) and the OLCI Terrestrial Chlorophyll Index (OTCI), which supply indication of the content of Chlorophyll in the vegetation canopy. This involves checking the data quality over each orbit cycle (27 days), spatial and temporal consistency over number of global sites and undertaking field campaign for direct validation.
