Our approach was to find a global scale factor that minimizes the differences between the AOT retrieved by satellites and the modeled AOT which is equal to the sum of AOT due to biomass burning and AOT due to other type of aerosols. We constructed and performed two modeling runs - one with biomass burning (R_ddQFED) and another with no biomass burning (R_mmNOBB). From these two runs we calculated the contribution of the biomass burning to the total AOT and found the optimal value of the global scale factor that minimized the difference between the observed AOT and the modeled AOT. As a first approximation the same factor was used to scale the QFED emissions. The derived in this way globally scaled QFED emissions were used in the R_ddQFED_MISR experiment. | Our approach was to find a global scale factor that minimizes the differences between the AOT retrieved by satellites and the modeled AOT which is equal to the sum of AOT due to biomass burning and AOT due to other type of aerosols.

Our observational AOT dataset was based on a 3-hourly globally gridded (2×2 degrees) MISR AOT spanning the 2003-2009 period. The decision to use MISR retrievals was primarily dictated by the robustness of the MISR aerosol retrievals algorithm over land. | Our observational AOT dataset was based on a 3-hourly globally gridded (2×2 degrees) [http://www-misr.jpl.nasa.gov MISR] AOT spanning the 2003-2009 period.
