The relationship between summertime ozone peak hour and NOx and VOC emissions Jianfeng Li April 21, 2016

A relationship between Ozone peak value and emissions A positive correlation between NOx emission and ozone peak value in the United States.

Do we expect a relationship between ozone peak hour and emissions? China, from Hang Qu

Ozone observation sites distribution

Comparison between model and observations simulation REAM - OBS Use peak hour difference to adjust emission!

Future work Sensitivity test to check whether increasing or decreasing emission could lead to better peak hour comparison.
