Short abstract below:<\/p>\n

It has been suggested that forest fires will become more frequent\/intense with changing climate, which would increase aerosol\/gas emissions into the atmosphere. A better understanding of the relations between meteorological conditions, fires, and fire emissions will help estimate the climate response via forest fires. In this study, we use ERA5 meteorological products, including temperature, precipitation, and soil moisture, to explain the frequency of forest fires and the amount of radiant energy released per time unit by burning vegetation (fire radiative power, FRP).
\nWe explore the relationships between satellite-retrieved fire products and aerosol properties (aerosol optical depth, AOD), carbon monoxide (CO), formaldehyde (HCHO), and nitrogen dioxide (NO2) concentrations over the PEEX domain, which covers different vegetation zones (e.g. croplands\/grasslands, forest, arctic tundra) of Pan-Eurasia and China.
\nUsing a 21-year satellite record of the AOD and CO, an 18-year record of NO2, and a 16-year record of HCHO, we created background products of those variables over the PEEX domain.
\nWe calculated AOD\/CO, AOD\/HCHO, AOD\/NO2 satellite-derived total column enhancement ratios for observations influenced by wildfires.
\nWe analyse the concentrations of black carbon and absorbing organic carbon using ground-based AErosol RObotic NETwork.<\/p>\n
