The growing number of users and applications of satellite dervied vegetation products demands for an understanding of their accuracy and uncertainties. Here at Southampton we are responsible for the development and application of methods for the traceability of in-situ biophysical measurments required to validate land products dervied from Sentinel-2, Sentinel-3 and PROBA-V. These responsibilties are part of the Fiducial Reference Measurements for Vegetation (FRM4VEG) project, a project managed by ESA within the Copernicus Program.
In addition, EOBAS works with JRC and ACRI-ST on the project Ground Based Observations for Validation of Copernicus Global Land Products (GBOV). The aim of GBOV is to develop the largest sistematic and quality assured database of in-situ measurements for the validation of satellite dervied vegetation products such as the fraction of absorbed photosynthetically active radiation (FAPAR), fraction of vegetation cover (FCOVER) and leaf area index (LAI).
EOBAS is an Expert Support Laboratory (ESL) of the Sentinel-3 Mission Performance Centre (S3MPC). Within S3MPC EOBAS is in charge of the assessment of the Ocean and Land Colour Instrument (OLCI) land products such as the Terrestrial Chlorophyll Index (OTCI). The OTCI is an operational product surrogate of canopy chlorohyll content developed by the University of Southampton.
At EOBAS we have the skills and extensive experience using time-series of the satellite derived land products in a range of topics. For instance, we are interested in applying these set of skills and capabilities to understand vegetation phenology and its link to climate. In the agriculture sector we are interested in monitoring, modelling and estimating crop yield. In the insurance sector we are interested in the estimating and monitoring livestock forage quality. We are also interested in carbon modelling and dynamics. Our groupd developed the Southampton Carbon Flux (SCARF) model, a model that ingest satellite data to estimate gross primary production (GPP) at large spatial scales.
