Fig. 5From: Surface and aloft NO2 pollution over the greater Tokyo area observed by ground-based and MAX-DOAS measurements bridged by kilometer-scale regional air quality modelingTemporal variation of NO2 concentration by MAX-DOAS and model averaged over 0–1 km (each direction). The MAX-DOAS measured horizontal distance is also plotted. The range of model results showed simulated NO2 concentration within 4–24 km from Chiba University in each direction. Statistical scores are shown in the inset, and 1 h averaged MAX-DOAS observation and corresponded horizontal distance to observation were used for this analysisBack to article page
