Abstract
Since 1972, the German Environment Agency (UBA) has been measuring continuously CO2 concentration at Schauinsland station (southwest Germany, 1205 m asl). Because of its vicinity to biogenic and anthropogenic sources and sinks, the Schauinsland CO2 record shows considerably variability. In order to remove these disturbances and derive the large-scale representative "background" CO2 levels for the respective area (southwest Germany) we perform rigorous data selection based on wind speed and time of day. During the past 30 years, the selected CO2 mixing rations increased by 1.47 ppm per year, following the mean trend in midlatitudes of the Northern Hemisphere. The...
