Abstract

In order to study global and regional distributions of ozone and its pre- cursors, airborne experiments are regularly conducted by European insti- tutions. It has been shown that intertropical regions have an important influence on the global distributions of photooxidants. In this study, chemi- cal fields of ozone, carbon monoxide and nitrogen oxides obtained over Ivory Coast during TROPOZ I experiment (December 1987) are presented and discussed in connection with their dynamical context. 1 Introduction Ozone is a key element in atmospheric chemistry. In the troposphere, it is mainly produced by photochemical processes from various precursors (CO, CHU, NMHC) in presence of nitrogen oxides. One major environment prob- lem is related to tropospheric ozone increase, d
