Annual and monthly average estimations of PM2.5 in 3km*3km grids in Taiwan during 2006 to 2017 were uploaded. In each file, the variables ID, x, and y represnt the code of the gird, the Longitude of the center point of gird, the Longitude of the center point of gird, respectively; the variable datetime is in form of yyyymm; the variable final_PM25 represents the estimated monthly average PM2.5 concentration (ug/m3).
The database was producted by our work as below: "Estimating ground-level PM2.5 levels in Taiwan using data from air quality monitoring stations and high coverage of microsensors", May 2020 Environmental Pollution 264:114810, DOI: 10.1016/j.envpol.2020.114810.
