Atmospheric Chemistry and Physics

The Pan European Gas AeroSOls-climate interaction Study (PEGASOS) European large scale integrating project brings together most of the leading European research groups, with state of the art observational and modeling facilities to:

1. Quantify the magnitude of regional to global feedbacks between atmospheric chemistry and a changing climate and to reduce the corresponding uncertainty of the major ones.
2. Identify mitigation strategies and policies to improve air quality while limiting their impact on climate change.

The project will combine development of anthropogenic and biogenic emission inventories, laboratory studies in some of the premier European smog chamber facilities, field measurements over Europe using a Zeppelin combined with mobile and fixed ground platforms, air quality and climate models, and policy analysis to achieve its objectives.
