“…This perturbation function is then applied to GFEDv2 emissions to obtain daily estimated emissions without altering monthly emissions, similar to the approach used by Heald et al [2003]. This approach has been demonstrated to improve the accuracy of atmospheric simulations as opposed to using monthly averaged emissions [ Hyer et al , 2007; Roy et al , 2007]. Biomass burning data at 1° × 1° resolution are smoothed with a 7 day moving average to reduce the effect of a periodic bias associated with the polar orbit of MODIS [ Heald et al , 2003] and are regridded onto the 2° × 2.5° UMD‐CTM grid.…”

“…Emissions of O 3 precursors (VOCs and NO x ) from wildfires are highly variable and depend on the fuel and fire conditions with average molar VOCs/NO x ratios from 15 for savannahs to 150 for boreal forests (Akagi et al, 2011). Furthermore, the chemistry of VOCs/ NO x irradiated mixtures is non-linear and challenging to describe due to large number of VOCs and high emissions uncertainties (Roy et al, 2006). However, the variability in net O 3 production caused by fire emissions and photochemistry is reduced as plumes travel away from the fire due to transformations of NO x to PAN and VOCs to alkyl (R), alkoxy (RO) and alkylperoxy radicals (RO 2 ) within a few hours and vertical/horizontal mixing.…”

“…Some studies [10,44] indicated that the poor temporally-allocated wildfire emissions may contribute to the biases in OC and EC predictions. Several studies based on 1999 NEI v3 indicated underestimation in wildfire emissions [8,45]. The emissions of EC and POA from the 2002 NEI v3 are much lower than those from the 1999 v3, particularly in the western US, indicating a possible underestimation in wildfire emissions to a greater extent than the 1999 v3 in this region, due likely to the use of older fuel loading information (George Pouliot, US EPA, personal communication, 2011).…”
