Boreal forest fires in 1997 and 1998: a seasonal comparison using transport model simulations and measurement data
International audience Forest fire emissions have a strong impact on the concentrations of trace gases and aerosols in the atmosphere. In order to quantify the influence of boreal forest fire emissions on the atmospheric composition, the fire seasons of 1997 and 1998 are compared in this paper. Fire...
