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. %@mirrorrepository sid.inpe.br/mtc-m18@80/2008/03.17.15.17.24 %T Validation of the LSA-SAF land surface emissivity product using modis data %@format On-line %@tertiarytype Poster %@secondarytype PRE CI %8 8-12 sep. %@visibility shown %@e-mailaddress deicy@cptec.inpe.br %@secondarykey INPE--PRE/ %2 sid.inpe.br/mtc-m18@80/2009/05.21.19.45.44 %4 sid.inpe.br/mtc-m18@80/2009/05.21.19.45 %D 2008 %A Peres, Leonardo F., %A Libonati, Renata, %A DaCamara, Carlos C., %C Darmstadt, Germany %@area MET
