“…Vast areas and the inaccessibility of many territories exposed to wildfires complicate early fire detection and assessment of its effects. Therefore, taking into account the features and scales of these phenomena, satellite methods and technologies appear promising to address the problem of detecting sources of wildfires and assessment of their effects (Bondur, 2011;Bondur, 2016;Bondur et al, 2017;Bondur et al, 2019a;Bondur et al, 2019b;Bondur et al, 2020a).…”

“…Low-resolution satellite data from Terra, Aqua, NOAA, Suomi NPP, FengYun-3, Meteor-M, and other satellites are the main sources of fresh data on wildfires in large areas (Bondur, 2016;Bondur et al, 2019a;Bondur et al, 2020a). The use of such higher frequency data allows to detect fires quickly even on remote territories.…”

“…The use of such higher frequency data allows to detect fires quickly even on remote territories. This is especially important for the monitoring of wildfires and assessment of volumes of wildfire emissions into the atmosphere in order to take timely measures to ensure safety and prevent negative effects of these natural phenomena (Pu et al, 2004;Bondur, 2011Bondur, , 2016Giglio et al, 2016;Bondur et al, 2017, Bondur andGordo, 2018;Bondur et al, 2019b;Bondur et al, 2020a).…”

Here we present the results of satellite monitoring of wildfires in Australia for the period of 2001–2020. Annual and monthly dynamics of wildfire areas and CO and CO2 carbon-bearing trace gas emissions from wildfires have been analyzed for the whole territory of Australia based on satellite data. It was found that anomalous fires occurred in the territory of New South Wales during the 2019–2020 fire season. Values of burned-out areas exceeded the values of previous years 3.5–25.8-fold. Annual mean volumes of carbon-bearing gas emissions in this region exceeded the values of previous years 4–59-fold for carbon monoxide CO and 4.6–50-fold for carbon dioxide CO2. The spatial distribution of the excess concentrations of CO from wildfires in New South Wales was recorded according to the monthly mean data of the AIRS instrument (Aqua satellite). At the same time, the excess of CO2 concentration in the atmosphere was estimated using the TANSO-FTS (GOSAT satellite) data. It was demonstrated that an anomalously high number of fires in this state of Australia was caused by extreme drought associated with abnormally high surface temperatures, low rainfall and humidity which created conditions for intense fires and emissions of carbon-bearing gases associated with the combustion of eucalyptus and tropical rain forests prevailing in this region.

A structure of an automated aerospace monitoring system for monitoring of forest fires and a model for the joint use of satellite monitoring data of the forest fire situation in Russia and clarifying observations of unmanned aerial vehicles are proposed. A comparison of the effectiveness of each of the methods separately is carried out and an assessment of the improvement of the quality of control when they are used together is given. It is shown at the theoretical level that aerial monitoring using satellite observation data gives a significant reduction in the average time to detect a forest fire. To simulate the movement of unmanned aerial vehicles (UAVs), a non-stationary multidimensional Fokker-Planck equation is used with varying diffusion and drift coefficients, determined both by the initial goal of the flight task and by local measurements of gradients of atmospheric parameters (smoke content, temperature). The simulation principle is formulated, which is proposed to be the basis for the optimization of the projected aerospace monitoring system.
