AB: Observations of aerosol in the lower stratosphere during northern summer indicate that aerosol is transported from the lower troposphere into the stratosphere due to intense Boreal fires. Observations of Siberian fires in the Spring of 2003 are discussed to illustrate how multi-platform data can be used to study these events. MODIS aerosol optical depths,MOPITT CO mixing ratios, and POAM aerosol extinction data are used in an analysis of the Spring 2003 fires. Aerosol and CO is injected into the troposphere, and enhanced POAM aerosol appears in the lower stratosphere, in May. A historical perspective is given based upon POAM, SAGE, and TOMS data for years between 1985 and 2000, excluding 1991-1995(the period of time in which Pinatubo aerosol was influential). Toms aerosol optical depths at latitudes between 50 and 70 N are large (due to Boreal fires) during the same years in which enhanced aerosol extinction is also observed several km above the thermal tropopause. The longitudinal distribution of the aerosol enhancements in the lower stratosphere shows a preference for longitudes over eastern Siberia.
