Abstract

In 1995, S. Sillman developed the photochemical indicators concept for identifying ozone chemical regimes. This concept was only applied and validated for American atmospheric situations. As part of the ESQUIF campaign, we have calculated H2O2/HNO3, O3/NOy, O3/NOz indicators for the Ile de France area. The chemistry-transport 3D model A3UR, developed by IFP, LISA and EDF was used. We compared transition values found for the Paris area to those proposed by S. Sillman as universal ones. Our results make us think that indicators transition values depend on the atmospheric situation studied.
