Abstract

This study attempts to analyse the spatial and temporal variations of biomass burning and concurrent carbon monoxide mixing ratios across the Indian region, over a period of two years (2016-17). We leverage data from the Moderate Resolution Imaging Spectrometer (MODIS) instruments Aqua and Terra, to study the variations of fire counts over the study region. Carbon Monoxide (CO) mixing ratios at 925 hPa are investigated using data from the Atmospheric Infrared Sounder (AIRS). The study region is further divided into four sub-regions (North, Centre, South, and North-East), and the variations in biomass burning activity are studied. Additionally, comparisons between MODIS Aqua and Terra fire counts are made. We analyse fire counts and CO mixing ratios over two different temporal resolutions, monthly and seasonal, and attempt to understand the relationship between the two.
