Description
Summary:Rapid industrial and economic development over the past two decades in India leads the high levels of air pollution. Carbon monoxide (CO) is one of the main pollutants, is not only harmful for human beings but also for its impact on climate. The major CO sources in India are biomass burning and vehicular emissions. Here we used Measurement of Pollution in the Troposphere (MOPITT) CO data from 2005-2015 to examine CO sources, interannual variability, and transport pathways over India. We observed that during the winter months CO emissions over eastern part of Bihar, west Bengal and Northern Indo Gangetic (IG) plain are much higher than during the summer months. The increased vehicular emissions and industrial activity after 2010 resulted in increased CO in the same regions. CO mixing ratios at 350 hPa lowered at 68-90 µg m −3 over Arabian Sea and approximately 90 µg m −3 over Bay of Bengal during Indian summer monsoon. Deep convective activities transported maximum CO pollutants up to 200 µg m −3 over northern and eastern part of India during monsoon season.
