Abstract
Considered to be a global hotspot of elevated aerosol loading, the densely populated north Indian region is one of the few to experience enhancements in fine particulate matter (PM2.5, small particulate matter of 2.5 microns or less in diameter). The World Health Organization and the Indian Central Control Board daily threshold for unhealthy air being often exceeded, PM2.5 poses significant health risks, reduces visibility and has strong climate impacts. Due to the crop residue burning practice, PM2.5 emission spikes are observed in the post-monsoon season, during the months of October and November. Using the Fire INventory of the National Center for Atmospheric Research (NCAR) version 1.0 (FINNv1), and through plotting a time series of daily fire emission values as well as analysing FINN maps of north-India, this paper develops an understanding of the evolution of fires. Along the Indo-Gangetic Plain, emissions tend to increase after 2009, year marking the promulgation of the Punjab and Haryana groundwater acts of which unintended consequences strengthened air pollution enhancements. Additionally, emission peaks have shifted to the first fortnight of November, a period during which conditions lead to atmospheric stability and thus hinder air pollution dispersion.
