The statistical tools such as empirical orthogonal function (EOF), and singular value decomposition (SVD) have been applied to analyze the characteristic of air pollutant over southeast Asia well evaluate Zimeke's tropospheric column ozone (ZTO) determined by residual method. In this study, we found that EOF SVD analyses are useful methods extract most significant temporal spatial pattern from enormous amounts satellite data. with OMI <TEX>$NO_2$</TEX> HCHO revealed showed high correlation fire count (r=0.8) analysis CO (r=0.7). This suggests biomass burning influences a major seasonal variability on region. ZTO has indicated location maximum was considerably shifted westward month occurred later than (March) <TEX>$NO_2$</TEX>, CO. For further analyses, performed between precursor examine their check consistency two variables. latitudinal gradient could result stratospheric in March appears be associated shows March. These results suggest there some sources error method cloud height error, low efficiency ozone, accuracy lower ozone.
