The atmosphere is changing and the potential consequences for the "System Earth" are manifold. Dynamics, chemistry, and radiation determine its state and because all are coupled with each other via various mechanisms it is often difficult to identify a direct link between causes and consequences. A better understanding of this system requires integral, continuous, precise, long term and global observations. In order to contribute to this effort of improved understanding, the World Data Center for Remote Sensing of the Atmosphere (WDC-RSAT) was established. ... more


Mapping snow cover over Europe using AVHRR data

The AVHRR Processing scheme Over cLouds Land and Ocean (APOLLO) is operationally used at DLR to separate cloud free, cloudy and snow covered pixels. A simple algorithm collects cloud free and snow pixels to map the snow cover over Europe. Each received AVHRR overpass (at DLR Oberpfaffenhofen) contributes to the map: A map-pixel is set to cloud free if the corresponding pixel in the actual overpass has been detected cloud free. A map-pixel is set to snow if any snow-contamination has been detected. Wherever clouds without information on snow are present, the status is kept unchanged. The current snow cover over Bavaria is provided here
