Based on the observation data of solar scattering spectrum obtained by the multi-axis differential absorption spectroscopy (MAX-DOAS) in Huaibei area, China, from December 8 to December 31, 2018, the tropospheric NO2 vertical column density was retrieved, and the diurnal variation of NO2 concentration under different weather conditions in winter was analyzed. It is found that the high NO2 concentration occurrs in the period from December 18 to December 27, and the maximum daily average value appears on December 27, which is about 2.9 times of the lowest daily average. Combined with the wind field trajectory model, the wind field under different atmospheric conditions was studied. It is found that the northerly wind field is mainly in the period of low NO2 concentration, and the southerly wind field increases when NO2 concentration is high, which means that the pollution generated in the urban area is transported to the observation area. Moreover, the results of MAX-DOAS were compared with those of OMI satellite results, and it is found the two results show good consistency (R2=0.88).
