Abstract

Scattered sunlight Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) has been successfully applied to the quantitative determination of trace gas abundances in clean and polluted environments (e.g. to measure halogen oxides in polar regions, or SO₂, NO₂, CH₂O, glyoxal, and HONO in urban air) In particular volcanic plumes have been analysed for SO₂, BrO, and other species. We present and discuss promising options for the quantitative analysis of all above mentioned trace gases in biomass burning plumes, in particular in forest fire plumes. The technique allows of the total emission burden in the plume with extremely simple and compact ground - based instruments, which also can be operated automatically. Combining the measured column densities with wind speed data the total trace gas flux from the fire can be determined with good accuracy. A few examples for possible applications of the technique to monitor fire properties are given.
