2.4.3 Atmospheric Composition 
The following gives some explanation for each row of Table 1c). 
World Meteorological Organization / Global Atmospheric Watch (WMO / GAW) Global At 
mospheric C0 2 and CH 4 Monitoring Network: 
Generally there are four stations observing these variables: the two GAW regional stations 
Schauinsland and Neuglobsow, Neumayer (also part of GSN and GUAN networks) and the 
station Zugspitze/ Schneefernerhaus. 
The GAW Regional Station Neuglobsow only measures C0 2 and CH 4 concentrations. 
WMO / GAW ozone sonde network: 
The stations Lindenberg, Hohenpeissenberg, Neumayer and Ny Alesund/AWIPEV measure 
ozone with ozone-sondes. At Hohenpeissenberg in addition an ozone-Lidar is used to detect 
ozone. 
WMO / GAW column ozone network: 
Lindenberg, Hohenpeissenberg, Neumayer and Ny Alesund/AWIPEV are involved in the 
WMO / GAW column ozone network. 
WMO / GAW aerosol network:
