Sub-seasonal evolution of satellite-detected fire counts (a), normalized pattern of fire occurrence (b, left), and daily-averaged PM2.5 in New Delhi (b, right) during 2012–2016. The Gaussian fits to the observed fire count data are shown in the inset with parameters of the distribution tabulated in the lower-right of top chart. The Probability distribution function (PDF) of fire counts normalized to the total number of fires during the respective years (20120–2016) is shown in the inset; averaged (μ) PDF with the corresponding 1-standard deviation (σ) derived using the recent five years of data are shown in black ink.
