“…7 ) and AOD ( Fig. 3 ) anomalies is somewhat mixed with only Delhi showing a consistent decrease in both which may be linked to changes in residual burning practices in Punjab as well as reduced frequency of forest fire during the pre-monsoon season ( Gupta et al, 2020 ). Fig.…”

“…Significant reduction of 83,4 % in the cumulative fire incidences during 24 March to 5 May 2020 was observed in this region compared with corresponding period of 2006-2020. Though during the current lockdown period, precipitation was high (~281 mm) compared to the average for the last 15 years (~125 mm) [5].…”

Covid-19 it is a new problem of modern society that has changed the usual way of life and has made both negative and positive changes. The introduction of restrictions due to Covid affected and on the distribution of forest fires both within a year and between years. The analysis of works has shown that anthropogenic activity plays a major role in forest fire incidences. In this worked statistical data of forest fires in one of the Russia federal districts (Volga Federal District) in 2019 (during the period without Covid) and 2020 (period with Covid) years are analyzed. Such subjects as Perm Territory (high forest cover – 71,5 %), the Orenburg Oblast (low forest cover – 4,7%) and Republic of Bashkortostan (leader in the number of forest fires) have been studied in detail. The results showed that during the most fire-hazardous season in Russia, April-May, namely during the beginning of Covid-19, the number of forest fires significantly decreased due to restrictions on the people movement. But, with the weakening of the self-isolation mode and the onset of an abnormally hot summer, the number of fires has increased. Thus, anthropogenic activity plays an important role in the occurrence of forest fires in this region.

“…One exception is Sundarban (105 km from Kolkata), where no notable change was observed during the study period (2010-2020) (Table S5). Since anthropogenic activity was curbed across the country to contain the spread of COVID-19, the severity and extent of forest and nearby emissions were expected to dramatically decrease, as the vast majority of forest fires in India are due to anthropogenic activity [54]. This may affect the LST level in forests.…”

The unique geographical diversity and rapid urbanization across the Indian subcontinent give rise to large-scale spatiotemporal variations in urban heating and air emissions. The complex relationship between geophysical parameters and anthropogenic activity is vital in understanding the urban environment. This study analyses the characteristics of heating events using aerosol optical depth (AOD) level variability, across 43 urban agglomerations (UAs) with populations of a million or more, along with 13 industrial districts (IDs), and 14 biosphere reserves (BRs) in the Indian sub-continent. Pre-monsoon average surface heating was highest in the urban areas of the western (42 °C), central (41.9 °C), and southern parts (40 °C) of the Indian subcontinent. High concentration of AOD in the eastern part of the Indo-Gangetic Plain including the megacity: Kolkata (decadal average 0.708) was noted relative to other UAs over time. The statistically significant negative correlation (−0.51) between land surface temperature (LST) and AOD in urban areas during pre-monsoon time illustrates how aerosol loading impacts the surface radiation and has a net effect of reducing surface temperatures. Notable interannual variability was noted with, the pre-monsoon LST dropping in 2020 across most of the selected urban regions (approx. 89% urban clusters) while it was high in 2019 (for approx. 92% urban clusters) in the pre-monsoon season. The results indicate complex variability and correlations between LST and urban aerosol at large scales across the Indian subcontinent. These large-scale observations suggest a need for more in-depth analysis at city scales to understand the interplay and combined variability between physical and anthropogenic atmospheric parameters in mesoscale and microscale climates.
