AB: The Moderate-resolution Imaging Spectroradiometer (MODIS) provides global observation of aerosol onboard the Terra and Aqua satellites. The satellite data on AOD have been used extensively in the detection, aerosol loading estimation and movement tracking of the yellow sand events. Furthermore, the MODIS provides AOD with the fine mode fraction over ocean and darker land surfaces, but still have limitations to distinguish carbonaceous and sulfate aerosol. Measurement Of Pollution In The Troposphere(MOPITT) onboard the Terra satellite provides quantitative information of carbon monoxide(CO). Measurements of CO whose principal sources arise from anthropogenic emissions such as biomass burning and forest fires, is very useful for tracing fire emissions in the atmosphere. In this study, the satellite data from MODIS and MOPITT were used to analyze correlation between AOD and CO density for the intense fires in the southeast part of Russia in May, 2003, which have affected quality of atmospheric environment over Korea significantly. The AOD distribution from the MODIS for May, 2003 show movement of high AOD regions near the Korean Peninsula. The CO column densities from the MOPITT also show enhanced values for May, 2003. Reasonably good pattern correlation between CO and AOD are found over the source region of forest fire in particular. This multi-instrumental approach to monitor the aerosol in the atmosphere is expected to contribute to the classification of the aerosol characteristics in the atmosphere, carbonaceous aerosol in particular. Furthermore, as the lifetime of CO is long compared to that of aerosol in the atmosphere, the ratio of AOD to CO can be used to trace the emission source and sink regions in the atmosphere. This ratio is expected to be larger near the source region and smaller near the sink, because the aerosol is deposited to the ground leaving the CO in the atmosphere. These results are compared with the backward trajectory analysis by the HYSPLITT model of NOAA.
