Following the recommendations given at the Envisat Validation Workshop and responding to the need for the subgroups of the ACVT to have a meeting to discuss the results of the correlative data acquisitions and analysis and to derive the current status of the operational atmospheric chemistry products including refining the error bars, the (second) workshop on Atmospheric Chemistry Validation of Envisat (ACVE-2) has been held in May 2004. A third ACVE workshop is expected to take place in 2005
