In the tropics vegetation fires represent an important source of greenhouse gases and aerosols to the atmosphere. In Africa they are considered the main source of atmospheric emissions. Rose diagram approach is used to enhance the relationships between point data, such as atmospheric chemistry measurement sites, and spatially distributed phenomena, such as regional patterns of fires derived from satellite observations. A rose diagram atlas for Africa, covering the five years period 1984-89, has been compiled for twenty atmospheric chemistry measurements sites. A selection of these sites, whose location is of particular interest for some international programmes studying tropospheric (EXPRESSO) and precipitation (IDAF) chemistry, is presented in this document.
