Fig. 4

Temporal variation in hourly NO2 concentration at the surface level along 4AZ-MAX-DOAS measurement paths. Ground-based observation by AEROS and the model results are shown. AEROS sites are named in order of nearness to Chiba University in each direction. Statistical scores are shown at the top-right of each panel. Yellow highlighting denotes high NO2 concentration defined as greater than 30 ppbv. See also Fig. 1
