Cabauw Intercomparison Campaign of Nitrogen Dioxide measuring Instruments

A CEOS, GEOMON, ACCENT-AT2 and NDACC initiative


Cabauw, The Netherlands, June-July 2009

The main objective of this campaign is to intercompare the NO2 measuring instruments that can be used for validation of tropospheric NO2 from satellites. The campaign should result in an estimate of the accuracy of the NO2 tropospheric columns and profiles for the participating instruments under different atmospheric conditions (clouds/aerosols) and viewing geometries. Many different in-situ and remote sensing instruments will participate. Apart from NO2, other parameters will be measured and intercompared, among which O3, aerosol, HCHO, CHOCHO, and BrO.
