Short summary
We carried out 19 city-circle-around Car MAX-DOAS experiments on the 6th Ring Road of Beijing in Jan, Sep, and Oct 2014. The tropospheric VCDs of NO2 are retrieved and their temporal and spatial distributions are investigated. Then the NOx emission rates in urban Beijing are estimated using the measured NO2 VCDs together with the refined wind fields, NO2-to-NOx ratios, and NO2 lifetimes simulated by the LAPS-WRF-CMAQ model system, and results are compared with the MEIC inventory in 2012.
