                         (LSA-SAF) is currently deriving, on an operational basis, maps of 
                         land-surface emissivity (LSE) based on information provided by the 
                         Spinning Enhanced Visible and Infrared Imager (SEVIRI) on-board 
                         METEOSAT-8. Delivered information includes a quality control (QC) 
                         label based on validation results. Validation activities should 
                         preferably be performed by comparing satellite-derived data with 
                         ground reference measurements e.g. obtained during field 
                         campaigns. However, validation of the LSA-SAF LSE product by means 
                         of comparisons between data retrieved from satellite and from 
                         in-situ point measurements has proven to be especially 
                         challenging. The major problem relates with the scale mismatch 
                         between ground point measurements (3 to 50 cm) and the SEVIRI 
                         resolution (about 5 km). We present a different validation scheme 
                         that relies on the 5-km MODIS LST/LSE product to assess the 
                         overall consistency of the LSE maps from the LSA-SAF.",
