We investigate the temporal evolution of the important tropospheric air pollutant nitrogen dioxide (NO2
) since the early 2000s, and correlate NO2
abundances with indicators of economic development. Until 2012, NO2
pollution and economic growth are strongly correlated, with annual increases of up to 4.4 %. Since then, tropospheric NO2
pollution has stabilized or is even declining, probably as a result of a slow-down in Indian economic growth combined with the implementation of cleaner technology.
