To control the severe air pollution during the season, comprehensive regional joint-control strategies were implemented throughout a campaign. To evaluate the effectiveness of these strategies and to provide some insights into strengthening the regional joint-control mechanism, the influence of control measures on levels of air pollution was estimated with an integrated measurement-emission-modeling method. To determine the influence of meteorological conditions, and the control measures on the air quality, in a comprehensive study, the 2nd World Internet Conference was held during 16–18 December 2015 in Jiaxing City, Zhejiang province, in the Yangtze River Delta (YRD) region. We first analyzed the air quality changes during four meteorological regimes and then compared the air pollutant concentrations before, during, and after the regulation under static meteorological conditions. Next, we conducted modeling scenarios to quantify the effects caused due to the air pollution control measures. We found that total emissions of SO2, NOx, PM2.5, and volatile organic compounds (VOCs) in Jiaxing were reduced by 56 %, 58 %, 64 %, and 80 %, respectively, while total emission reductions of SO2, NOx, PM2.5, and VOCs over the YRD region are estimated to be 10 %, 9 %, 10 %, and 11 %, respectively. Modeling results suggest that during the campaign from 8 to 18 December, PM2.5 daily average concentrations decreased by 10 µg m−3 with an average decrease of 14.6 %. Our implemented optimization analysis compared with previous studies also reveals that local emission reductions play a key role in air quality improvement, although it shall be supplemented by regional linkage. In terms of regional joint control, implementing pollution channel control 48 h before the event is of most benefit in getting similar results. Therefore, it is recommended that a synergistic emission reduction plan between adjacent areas with local pollution emission reductions as the core part should be established and strengthened, and emission reduction plans for different types of pollution through a stronger regional linkage should be reserved. </jats:p> Evaluation of the effect of regional joint-control measures on changing photochemical transformation: a comprehensive study of the optimization scenario analysis Atmospheric Chemistry and Physics |

<jats:p>Abstract. Heavy haze usually occurs in winter in eastern China. To control
the severe air pollution during the season, comprehensive regional
joint-control strategies were implemented throughout a campaign. To evaluate
the effectiveness of these strategies and to provide some insights into
strengthening the regional joint-control mechanism, the influence of control
measures on levels of air pollution was estimated with an integrated
measurement-emission-modeling method. To determine the influence of
meteorological conditions, and the control measures on the air quality, in a
comprehensive study, the 2nd World Internet Conference was held during
16–18 December 2015 in Jiaxing City, Zhejiang province, in
the Yangtze River Delta (YRD) region. We first analyzed the air quality
changes during four meteorological regimes and then compared the air
pollutant concentrations before, during, and after the regulation under
static meteorological conditions. Next, we conducted modeling scenarios to
quantify the effects caused due to the air pollution control measures. We
found that total emissions of SO2, NOx, PM2.5, and volatile organic compounds (VOCs) in
Jiaxing were reduced by 56 %, 58 %, 64 %, and 80 %, respectively,
while total emission reductions of SO2, NOx, PM2.5, and VOCs
over the YRD region are estimated to be 10 %, 9 %, 10 %, and 11 %,
respectively. Modeling results suggest that during the campaign from
8 to 18 December, PM2.5 daily average concentrations decreased
by 10 µg m−3 with an average decrease of 14.6 %. Our implemented
optimization analysis compared with previous studies also reveals that local
emission reductions play a key role in air quality improvement, although it
shall be supplemented by regional linkage. In terms of regional joint
control, implementing pollution channel control 48 h before the event is
of most benefit in getting similar results. Therefore, it is recommended
that a synergistic emission reduction plan between adjacent areas with local
pollution emission reductions as the core part should be established and
strengthened, and emission reduction plans for different types of pollution
through a stronger regional linkage should be reserved.
