The BlueSky Science Team will employ NASA Earth Science results to reduce key uncertainties affecting models of air pollutant emissions and transport from biomass burning. Previous work has identified the largest smoke modeling sensitivities as (1) errors in consumption rates due to incorrect or inappropriate (dead and live) fuel moisture assumptions, and (2) vertically misplaced plume injection heights. The proposed project will employ NASA results to address these uncertainties: (1) dead fuel moisture estimates over the conterminous United States will be improved through the daily incorporation of the TRMM Multisatellite Precipitation Analysis real-time (TMPA-RT) data set; (2) EastFire live fuel moisture estimates derived from MODIS direct broadcast data over the conterminous United States will be incorporated; and (3) plume injection heights will be constrained and adjusted based on algorithms derived from the MISR stereo heights combined wit h fire radiative power (FRP) from MODIS. Additionally, by incorporating the FLAMBE and FRP algorithms that can calculate fire emissions directly from fire detects and radiance measures from MODIS and GOES, we will be able to utilize both top-down and bottom-up calculation pathways to obtain a measure of the remaining uncertainty in fire emissions. This work will be done in the context of the BlueSky Smoke Modeling Framework and SMARTFIRE fire information systems currently used in numerous decision support applications at the local, regional, and national scale related to smoke, including: (a) wildfire suppression prioritization; (b) prescribed burning go/no-go decisions; (c) airshed management; (d) public health notifications; and (e) creation of the U.S. National Emissions Inventories. Because of these connections, this proposal will directly benefit wildfire firefighting efforts, land management, air quality management, public health information, and emissions policies at the regional, tribal, state and federal, and international levels. By also incorporating the ability to use planned satellites, these benefits will last well beyond the lifetime of the project.
