Hello everyone,

I have been looking for air pollution (CO2, PM10, Ozone, etc) data for the United States by County level for one project, "The Effect of Air Pollution on Housing Prices in the SouthWest of USA".

I have collected data from the EPA website though it contains the number of days and air quality index with the above variables. I would like to use a yearly average of these variables in ktons or metric tons by county level. I have heard that EPA might be managed this type of data. However, I have a very hard time finding from their website.

I can see that EDGAR is collecting the air pollution data from 1970-2015 by Country. I can only get the national-level data for the USA from this website, which does not help me at all.

Could anyone please recommend any website, source to me that I can use for collecting the data?

Thanks in advance,

Samsun
