"Space and climate change" meeting - Paris - July 4th 2008

CNES organised on July 4th 2008 in its Parisian facilities a meeting about "Space and climate change".

The space tool takes a particular ranking in the data collecting device giving a global and sustained vision as a complement for in situ data. When France hold the Presidency of the European Union, CNES though it would be important to provide an update of the ways of improving our climate scenario forecasting capacities as well as the evaluation of the public adaptation policies' effects.

This meeting, organised around some scientific experts' presentations, was the occasion to emphasize the contribution from space to the climate change observation. It was also the occasion to point out the long and mid term prospects with regard to priority missions in the context of the European space programmes (UE, ESA, Eumetsat, Member States).

Presentations of the scientific experts (all in French)

1 - P-Y Le Traon: "Ocean and climate: contribution from space observations"

P-Y Le Traon is head of the Ocean observatory programme at IFREMER. Before, he was Vice-President of the Space Oceanography division of the CLS company. P-Y Le Traon is co-responsible for the Global Ocean Data Assimilation Experiment (GODAE) and member of several international and European scientific groups on ocean observation. He coordinates the European contribution to the Argo international network for the ocean observations by profiling floats (Euro-Argo). He also assists the space agencies (CNES, European Space Agency, Eumetsat) and the European Union for their missions involving space oceanography.

2 - O. Boucher: "Contribution from space observations to the atmosphere study"

O. Boucher is Director of Research at the CNRS and is currently on detachment to the Met Office Hadley Centre where he leads the team in charge of the atmospheric chemistry, ecosystems and Earth system modelling. He is also affiliated to the Atmospheric Optics Laboratory where he acquired an experience in remote sensing and model validation.

3 - F. Rémy: "The polar ices seen from space"

F. Rémy, polar area expert, is director of research at the CNRS and responsible for the "cryosphere" team at the Observatory of Midi-Pyrénées. Her research has addressed the glacier and ice cap remote sensing to study the ice dynamics and response to the climatic variations. She is the author of "l'Antarctique, la mémoire de la Terre vue de l'espace" (Antarctica, the Earth's memory seen from space), published in 2003 by CNRS - éditions, and "Histoire de la glaciologie" (History of glaciology), published in 2007 by Vuibert.

4 - W. Cramer: "Land-use change - Challenge for the Earth Observation and modelling"

W. Cramer, geographer and ecologist, is a professor of ecology at the university of Potsdam (Germany) and director of the Earth System Analysis division at the Potsdam Institute for Climate Impact Research. In 2007/2008, he was research associate at CEREGE (Air-en-Provence, France). IPCC member, he was also co-author/publisher of the Millennium Ecosystem Assessment and 2nd, 3rd and 4th IPCC reports.
