Extending ozone-precursor relationships in China from peak concentration to peak time

Observation data is obtained from the CNEMC website (http://www.cnemc.cn). Simulation results are processed from the output of the REAM model. The code of the 3-D REAM is available on https://github.gatech.edu/Apollo/3D-REAM.观测数据取自中国国家环境监测中心（China National Environmental Monitoring Centre，CNEMC）官方网站（http://www.cnemc.cn）。模拟结果由REAM模型的输出数据经处理得到。三维REAM模型的代码可在https://github.gatech.edu/Apollo/3D-REAM获取。
