Beatriz Martinez (University of Valencia) - LSA SAF Vegetation products
Beatriz Martinez shows how climate data records analysis can be used to monitor drought affected areas.
The scientific community requires consistent long-term data records with well-characterized uncertainty and suitable for modelling terrestrial ecosystems changes as consequence of current climate impact at global scales. The vegetation climate data records (CDRs) of FAPAR (LSA-426) and FVC (LSA-422) are freely available within the EUMESAT LSA SAF (http://lsa-saf.eumetsat.int). These CDRs offer more than fifteen years (2005- present) of homogeneous and continuous 10-day time series for climate and environmental applications. The main goal of this lecture is to present a few examples CDRs analysis to monitor and characterize areas mainly affected by severe drought events. Moreover, the potential in the assessment of ecosystem response to rainfall deficit events is also presented using the last operational product included in the VEGA portfolio, the 10-day gross primary production (GPP; MGPP LSA-411). The robustness of this product is evaluated at both site and regional scales across the MSG disk using eddy covariance (EC) GPP measurements and Earth Observing (EO)-based GPP products, respectively, over a short period of three years.
