D-SDA has been archiving data of the Advanced Very High Resolution Radiometer (AVHRR) on board of the National Oceanic and Atmospheric Administration (NOAA) fleet of Polar Operational Environmental Satellites (POES) since 1983. For three decades DLR has been generating and archiving regional coverages of daily AVHRR level 3 products such as vegetation index, sea surface temperature and land surface temperature. D-SDA is now making available a subset of its AVHRR level 3 data archive via geospatial web services provided by the EOC Geoservice. "AVHRR - Monthly Mediterranean SST" is an AVHRR subset from 1993 to 2014 integrated in the EOC Geoservice to facilitate valuable time series exploitation of historic data. Additionally, integrating these data serves as a prototype for the DLR "TIMELINE" project.
