Study on Measurement of Troposphereic NO2 in Beijing by MAX-DOAS
Figures & Tables(9)
Fig. 2. Time-series distribution of monthly mean values of verticalcolumn concentration of troposphere NO2 in 2018
Low (high) error bars indicate that 10% (90%) of the overall date corresponds to date points, and solid points indicate the mean value
Fig. 3. The average daily change of NO2 VCD in the troposphere in different seasons in 2018
The low (high) error bar indicates that the overall date corresponds to 25% (75%) of the data point, and the solid point indicates the mean value
