The aerosol optical depth is detected at the four stations Lindenberg, Hohenpeissenberg, 
Zingst (a GAW regional station), and Zugspitze/ Schneefernerhaus. 
Other aerosol properties are additionally measured at Schauinsland, Neuglobsow, Neumayer 
and Ny Alesund/AWIPEV. At Lindenberg only the optical depth is measured but no other 
components.
