The amount of particles in the air is monitored by a Precision-Filter-Radiometer (PFR) sun photometer. providing aerosol optical depth (AOD). High sampling frequency gives valuable data for the examination of episodes caused by long-range transport of pollutants as well as a good basis for the study of trends and global atmospheric change. Most of the data is available from http://ebas.nilu.no/. A powerful tool in the analysis of episodes is the FLEXPART model (lenke).  

The station at Zeppelin Mountain is also used for a wide range of other measurements, which are not directly related to climate gas monitoring, including daily measurements of sulphur and nitrogen compounds (SO2, SO42-, (NO3- + HNO3) and (NH4+ + NH3), main compounds in precipitation (performed in Ny Ålesund), total gaseous mercury, particulate heavy metals, persistent organic pollutants (HCB, HCH, PCB, DDT, PAH etc.) in air, as well as tropospheric ozone. Zeppelin observatory is also widely used in campaigns as during the International Polar Year.
