This work presents a methodology and results from analyzing measurements CO from MOPITT from the past 17 years (2000-2016) over Southeast and East Asia. We analyze the CO total column and mixing ratio profile where the degree of freedom is in high value, focusing on those regions which are heavily influenced by large-scale biomass burning and intense urban pollution, to understand the change of the vertical, temporal and spatial distribution, and how the polluted emission from long distant impact the in-situ by long-range transport. Result indicate the biomass burning emission mainly dominate from Myanmar and Bangladesh through Thailand, Laos, and Vietnam, where are heavily polluted only during certain times of the year, while the urban emission mainly dominate from Jingjinji, Shandong, and Northern Jiangsu, Anhui, and Henan, where are always polluted. Additionally, the polluted emission from the biomass burning in Myanmar and Bangladesh spread and impact the downwind area strongest at the 800/700mb pressure level in the whole levels.
