The monitoring site at Garmisch-Partenkirchen is considered a grassland valley site. Because of strong local influence (vegetation and meteorology), the CO2 concentrations at Garmisch-Partenkirchen are higher and show greater seasonal amplitudes than the concentrations measured at Wank or Zugspitze. According to the filtered data, the annual atmospheric CO2 concentrations at Garmisch-Partenkirchen increased from 330.2 ppmv in 1978 to 345.1 ppmv in 1986 and from 347.6 ppmv in 1988 to 354.7 ppmv in 1992. The monitoring site at Wank Peak (WMO-BAPMoN station) is located on the grass-covered, rounded top of the mountain, just above the timberline. The mean annual CO2 concentrations at Wank Peak increased from 334.2 ppmv in 1980 to 348.6 ppmv in 1992. The station at Zugspitze is located near the summit of the highest mountain of the German Alps. In 1990, the site of CO2 sampling was changed from a location 250 m below the summit to a new monitoring station (2937 m above MSL) close to the mountain top. Compatibility of the results was seen from measurements conducted in parallel at the two sites for several months. Because of the high elevation of the mountain station, the CO2 measurements at Zugspitze can be considered free of regional contamination most of the time. The mean annual CO2 concentrations at Zugspitze increased from 333.7 ppmv in 1981 to 349.4 ppmv in 1992.For access to the data files, click this link to the CDIAC data transition website: http://cdiac.ess-dive.lbl.gov/trends/co2/fra.html
