Commission chimie et physique de l'atmosphère (CPA)

The ACP was newly founded in 2001 and emerged from the former Commission for Climate and Atmospheric Research (CCA). The CCA had given rise to the Forum for Climate and Global Change (ProClim), which dealt with climate research issues, so that this former area of work of the CCA lost importance as the topic gained prominence in an SCNAT forum. It was therefore decided within the CCA that no parallel structures to ProClim were necessary within the Academy of Sciences, and that a newly founded commission should take greater responsibility for atmospheric aspects outside of climate research.

These aspects primarily include air pollution issues, trace gas exchange between the biosphere and the atmosphere, aerosols, particulate matter, ozone, ammonia, NO_x, NO₂, etc., as well as atmospheric physics issues that do not fall within the narrower scope of climate research (meteorological research and development, basic research in the atmospheric field).
