1 Chemical scheme Reference scheme species reactions species reactions 530 species reactions Chemical schemes species reactions 150 species 506 reactions Secondary products surrogate species Primary species surrogate species Reduction of the peroxy radical types Chemical Operators Performances of the most reduced scheme tested by comparison with the reference scheme (box model / 8 scenarios from highly polluted to remote conditions) S. Szopa et al. ACPD, 5, , 2005

2 Results : urban scenario / winter Reference scheme Reduced scheme ±10% around results from explicit scheme

3 Results : regional scenario / summer Reference scheme Reduced scheme ±10% around results from explicit scheme
