AB  - The seasonal, interannual, and long-term variations in biomass burning activity 
      and related emissions are not well studied over South Asia. In this regard, 
      active fire location retrievals from the Moderate Resolution Imaging 
      Spectroradiometer (MODIS), the retrievals of aerosol optical depth (AOD) from 
      MODIS Terra, and tropospheric column NO2 from Ozone Monitoring Instrument (OMI) 
      are used to understand the effects of biomass burning on the tropospheric 
      pollution loadings over South Asia during 2003-2013. Biomass burning emission 
      estimates from Global Fire Emission Database (GFED) and Global Fire Assimilation 
      System (GFAS) are also used to quantify uncertainties and regional discrepancies 
      in the emissions of carbon monoxide (CO), nitrogen oxide (NOx), and black carbon 
      (BC) due to biomass burning in South Asia. In the Asian continent, the frequency 
      of fire activity is highest over Southeast Asia, followed by South Asia and East 
      Asia. The biomass burning activity in South Asia shows a distinct seasonal cycle 
      that peaks during February-May with some differences among four (north, central, 
      northeast, and south) regions in India. The annual biomass burning activity in 
      north, central, and south regions shows an increasing tendency, particularly 
      after 2008, while a decrease is seen in northeast region during 2003-2013. The 
      increase in fire counts over the north and central regions contributes 24 % of 
      the net enhancement in fire counts over South Asia. MODIS AOD and OMI 
      tropospheric column NO2 retrievals are classified into high and low fire activity 
      periods and show that biomass burning leads to significant enhancement in 
      tropospheric pollution loading over both the cropland and forest regions. The 
      enhancement is much higher (110-176 %) over the forest region compared to the 
      cropland (34-62 %) region. Further efforts are required to understand the 
      implications of biomass burning on the regional air quality and climate of South 
      Asia.
