A twelve days total column ozone intercomparison campaign was organized in collaboration with the Arosa Lichtklimatisches Observatorium (LKO) of MeteoSwiss during the period July 16 to 27, 2012 and with the participation of nine Brewer spectrophotometers from five countries. The intercomparison, as a part of the ESA funded project CEOS Intercalibration of Ground-based Spectrometers and Lidars, was a joint Brewer-Dobson exercise organized by the RBCC-E and the RDCC-E.

A preliminary report of Arosa 2012 intercomparison campaign is available from this link.
