The term “operational processors” refers to software-packages that continuously and in near-real-time generate well-defined (calibrated and validated) products from data records. Processors have to work largely without interactive intervention. In the context of ESA and EUMETSAT missions, EOC is in charge of the processor development for the ERS/GOME, ENVISAT/ SCIAMACHY and MetOp/GOME-2 spectrometers. This task comprises constant improvement of the algorithms and reprocessing of time-series for entire missions. The lidar mission ADM-Aeolus, dedicated to the derivation of global wind parameters, poses new challenges. In microwave remote sensing the focus is on generating terrain-corrected data and digital elevation models using radar interferometry. A new field of application is traffic monitoring in real-time. Processors are also used to routinely produce thematic maps, showing, for example, sea surface temperatures, vegetation indices, and suspended matter in water bodies, or for use in vulnerability assessments and fire detection.
