I am looking for any dataset for pollution (pollutant measurements co2, ozone, .. etc) at any city in US/Europe during 2014. Most of Datasets I found are old.

UPDATE

Datasets I found so far:

New York 1973: http://stat.ethz.ch/R-manual/R-devel/library/datasets/html/airquality.html

http://wonder.cdc.gov/wonder/help/pm.html

  • Can you post details & links for the outdated datasets? That will help people not post redundant answers. – philshem Jan 10 '15 at 16:10
  • Thanks! @philshem posted + I found commercial APIs as well. – user3378649 Jan 10 '15 at 16:14

The WHO provides global data for many cities. It doesn't seem to break down the overall air pollution into molecular components, though.

  • Website with details
  • Ambient (outdoor) air pollution database, by country and city (Excel file)

Many individual cities or regions provide air quality data. A short example, although basically every city or region will have some level of data or map available:

You may also find good data from the EPA (US) website:


Note that air pollution and greenhouse gases are different molecules and at different levels of the atmosphere. Air pollutants are often measured with PM (particular matter) sizes (wikipedia)

The composition of particulate matter that generally causes visual effects such as smog consists of sulfur dioxide, nitrogen oxides, carbon monoxide, mineral dust, organic matter, and elemental carbon also known as black carbon or soot.

If you are looking for only greenhouse gases, you may not find data with such accurate geolocation.
