Prediction of the Impact of Meteorological Conditions on Air Quality during the 2022 Beijing Winter Olympics
, Hailing Xi 3, Jiping Zhang 4 and Chengjun Zhou 1,5,*Round 1
Reviewer 1 Report
The authors used climate prediction data with weather circulation and meteorological elements to predict air quality during the 2022 Beijing Winter Olympics. This is a carefully done study that also contains valuable findings of the air quality modeling. This paper suffers, however, because the change of emission source and control strategy during the 2022 winter Olympics are unclear, the prediction of the air quality may contain a lot of uncertainty. The evaluation of the performance of the models based on monitoring data is suggested.

Please add WHO Air quality guideline values in Table1. (PM2.5: 15 μg/m3 24-hour mean, NO2: 25 μg/m3 24-hour mean)
3. Page 7, line 246-253
Please correct NO2 to NO2; SO2 to SO2
4. Page 10, line 321-324
“It is expected that the Beijing Municipal Government will further control emissions during the 2022 Winter Olympics”
The change of emission source and control strategy during the 2022 winter Olympics will impact the air quality. Please provide more information on control strategy during this period.

“By combining the average pollutant concentrations under each circulation pattern and the trends for the past seven years, we expect that the air quality during the 2022 Winter Olympics will be good.” Changes in emission sources and control strategies during the 2022 Winter Olympics will have an impact on air quality. Please provide more information on the control strategy during this period and assess its impact on air quality.
