Measurements
The GEOmon activity 2.1 focuses on surface observations of ozone, nitrogen dioxide and carbon monoxide. At most stations presented here, measurements of several other trace gases and aerosol parameters are also available but are not listed here. Refer to GAWSIS for more information on other parameters.
