A CEOS, GEOMON, ACCENT-AT2 and NDACC campaign organised in Cabauw, The Netherlands, June-July 2009.
Cabauw Intercomparison campaign of Nitrogen Dioxide measuring Instruments
The main objective of this campaign was to intercompare the NO2 measuring instruments that can be used for validation of tropospheric NO2 from satellites. The campaign resulted 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 participated. Apart from NO2, other parameters were measured and intercompared, among which O3, aerosol, HCHO, CHOCHO, and BrO.
