| Abstract: | The spatiotemporal variation in SO2 over the Bohai Sea during 2005 was analyzed from the planetary boundary layer (PBL) SO2 column densities retrieved from aura ozone monitoring instrument (OMI) data. Using the HYSPLIT model and FNL reanalysis data, the backward trajectories arriving in the Bohai Sea were calculated in order to identify the lead contributors. The obtained results indicate that the SO2 concentration over the Bohai Sea varies greatly with seasons, the mean concentration of SO2 shows the high values in autumn and winter, low values in spring and summer. the highest value which exceeds 6.187×1016 cm-2 in winter, the lowest concentration is 3.766×1016 cm-2 in summer; moreover the SO2 concentration varies greatly in the spatial distribution in different seasons. The results of the backward trajectory analysis show that SO2 emission from the region around the Bohai Sea has great influence on the Bohai Sea, the influence is the greatest in winter and the weakest in summer. |
