Short summary
We find rapid NO2 growth over Western China over 2005–2013 at a rate which exceeds the rates over the well-known polluted regions in the east. A nested GEOS-Chem simulation and Chinese official emission data confirm that anthropogenic emissions are the main driver of NO2 variations. Additional socioeconomic analysis suggests that this rapid NO2 growth is likely related to the fast industrialization and urbanization along with the "Go West" movement as well as relatively weak emission controls.
