This snapshot was taken in November 2004 by Peter's wife Morag at the occasion of the CCDAS meeting in Hamburg. It shows the entire core team with only Colin and Ernest missing. From left: Christian, Michael, Marko, Heiner, Jens, Martin, Thomas, Wolfgang, Peter, and Ralf.

A brief description of the role of CCDAS within the EU-FP5-project CAMELS has been prepared by Wolfgang Knorr and Peter Cox. It is part of the brochure that summarises the workshop Inverse modelling for potential verification of national and EU bottom-up GHG inventories" under the mandate of MMC-WG1, 23-24 October 2003, JRC Ispra.
