Detection of biomass burning combustion products in Southeast Asia from backscatter data taken by the GOME Spectrometer

摘要: We show that atmospheric UV/visible backscatter spectra obtained by the Global Ozone Monitoring Experiment (GOME) spectrometer on board ESA ERS-2 satellite may be used to retrieve column amounts of key trace species associated with smoke cloud combustion from biomass burning events. This paper focuses recent rain forest in SE Asia (August–October 1997). For ground scenes low cloudiness, differential absorption fitting applied yields distributions NO2 and H2CO around smoke-polluted regions. A two-fold increase vertical content is apparent over large parts cloud; this clearly indicates ability GOME measure tropospheric content. detected only areas closest sources. Slant range 2.5 - 4 × 1016 mol cm−2 have been determined; these correspond previous estimations columns for Savannah burning.
