The PM2.5 Concentration Monthly Dataset in Cities of China (2015) was developed based on more than 12 million air qualities monitoring raw data from 1,406 ground monitoring stations in 322 cities of China in 2015, the Kalman filter was used to do best estimation, and the peak signal-to-noise ratio was used to evaluate the effectiveness of the filtering results. The data includes monthly average PM2.5 concentrations and annual average PM2.5 concentrations in 322 cities of China in 2015. The dataset is archived in the .xlsx format with the data size of 614 KB in one file. The analysis paper related to this dataset was published on the Journal of Geo-information Science, Vol.19, No. 4, 2017.
