Global Dataset For Air Quality Index And Pollutant By Country (and City/state If Possible) Over The Years

Hi! I’m trying to look for a dataset for my university assignment.

I’d prefer if the dataset contains different pollutants such as PM2.5, PM10, O3, NO2, SO2, CO etc. The ones I found are usually either pollutants or AQI only, and in different formats so I can’t combine them easily.

(Optional) Would also be great if the dataset includes contextual data like Temperature, Wind Speed, Humidity, Source of Pollution etc

This would be a great help, thank you so much!!
