For my thesis I am looking for air pollution data. To be precise, I am
looking for the hourly Air Quality Index (AQI) variables for three
locations. These locations are in New York, London and Tokyo. From 1990
till 01/01/2020. Do you have any idea where I can find this data?
We would like to refer to the following websites that may be helpful for your research.
