Measurements:

- Synoptic (manual/automatic) and hourly (automatic) observations - Radio soundings (also O3, aerosol, H20 and radioactivity sondes)- Radiation measurements (eg. global, diffuse, reflected, direct, uv, aod)- Ground temperature measurements- Ozone satellite data centre (GOMOS instrument)- UV calibration laboratory- SAOZ instrument: O3, NO2 and OClO columns- Micro-wave radiometer laboratory - Aerosol lidar and ceilometer- Atmospheric electricity: current density, electric field, electrical conductivity- Radioactivity measurements (aerosol beta-activity, lead-210 and beryllium-7 samples)- Air quality measurements; surface O3 and deposition samples for measurement of some inorganic ions and pH.

Other measurements:

- Micrometeorological mast (eg. fluxes, profiles, ground and surface data, air quality)- Sodar (current campaign)- C-band weather radar
