While the vast majority of carbon emitted by wildland fires is released as CO2, CO, and CH4, wildland fire smoke is nonetheless a rich and complex mixture of gases and aerosols. Primary emissions include significant amounts of CH4 and aerosol (organic aerosol and black carbon),…

In many countries, prescribed or planned burning is increasingly used as a management strategy to reduce the risk and negative effects of wildfires. As a by-product of this practice, ash, charcoal and partially charred material (referred to here as pyrogenic carbon, PC) is…
