Analysis of satellite and reanalysis data indicates a relationship between pyrogenic NO2 emissions and atmospheric blocking events. According to the estimates for the period 2001–2019, with an increase in the integral blocking index by 10%, the total NO2 emissions into the atmosphere during wildfires in Russia increase by 0.7 million tons. Against the background of a general decrease in 2001–2019 of pyrogenic NO2 emission, a statistically significant increase in the NO2 emission density per unit area by 23% was revealed. At the same time, a decrease in the total emission of NO2 during wildfires was noted in relation to the corresponding emissions of carbon monoxide and fine aerosol.
