Potential of the EUMETSAT LSA-SAF Evapotranspiration for drought monitoring in Europe; a study developed in the framework of the European Drought Observatory

Published: 22 December 2014

The European Drought Observatory (EDO) (http://edo.jrc.ec.europa.eu) is an initiative of the European Commission’s Joint Research Centre that aims to integrate drought information at European level in a platform accessible to everyone. This information consists mainly in indices based in meteorological and remote sensing data that are produced in near real time.

During this lecture, the different indicators produced operationally at EDO will be firstly introduced. Secondly, a study developed at EDO assessing the LSA-SAF Evapotranspiration (ET) product for drought monitoring in Europe will be detailed. In this analysis, two case studies will be presented; corresponding to the drought episodes of spring/summer 2007 and 2011. For these two cases, the drought indicators previously introduced (Including ET) will be compared and analyzed, considering in the analysis, different drought effects as it is the decrease of the agricultural production.

Finally, the main limitations of the ET as drought indicator will be discussed, as well as the potential for drought assessment and monitoring of other LSA-SAF products like the Land Surface Temperature (LST) and the fraction of Absorbed Photosynthetic Active Radiation (fAPAR).
