2 Project Overview  Joint NASA/GMAO, NESDIS/STAR, and NWS/NCEP project to: »Develop near real time biomass burning emissions product covering the whole globe from polar and geostationary satellites for NEMS- GFS-GOCART –Globally, biomass burning is one of the primary sources of aerosols; burning varies seasonally, geographically and is either natural (e.g., forest fires induced by lightning) or human induced (e.g., agricultural burning for land clearing). Satellites can provide this information on a real time basis. »Develop and deploy a global aerosol prediction system that can in the future assimilate satellite-derived atmospheric composition parameters  Meet Research (NASA) to Operations (NOAA) goals of the JCSDA »QFED code transition from NASA to NOAA 2

Parameters a 1 -a 6 are scaling factors calculated by comparing year-long model-simulated AOD and MODIS AOD

7 NASA Quick Fire Emission Dataset (QFED) 7  QFEDv2—Calculated from MODIS FRP for various biome types and tuned using scaling factors which are obtained by comparing GFS-GOCART-modeled AOD with MODIS observed AOD.  Emissions are tuned respectively for Terra MODIS and Aqua MODIS, which are then combined to produce daily global emissions.  Final QFED product at 0.25x0.3125 degree is merged from Terra and Aqua daily fire emissions of BC, OC, SO2, CO, CO2, PM2.5

12 Calibration of Simulated FRP between GOES-E and GOES-W 12  Estimating satellite-scaling factor between GOES-E and GOES-W

13 Calibration of GBBEP-geo with Scaled QFEDv2 13 GBBEP-geo can be calibrated to be equivalent to QFEDv2 to generate global blended fire emissions because the QFEDv2 has been scaled using MODIS AOD.

14 14 Model Configuration:  Forecast model: Global Forecast System (GFS) based on NOAA Environmental Modeling System (NEMS), NEMS-GFS  Aerosol model: NASA Goddard Chemistry Aerosol Radiation and Transport Model, GOCART Phased Implementation:  Dust-only guidance is established in Q4FY12  Full-package aerosol forecast after real-time global smoke emissions are available and tested (JSDI project) NRT Dust Forecasts  5-day dust forecast once per day (at 00Z), output every 3 hour, at T126 L64 resolution  ICs: Aerosols from previous day forecast and meteorology from operational GDAS  GRIB2 products in 1x1 degree: 3-d distribution of dust aerosols (5 bins from 0.1 – 10 µm) and 2-d aerosol diagnosis fields (e.g., aerosol optical depth, surface mass concentration)  Operational since Sept 2012 NEMS GFS Aerosol Component (NGAC) NCEP’s global interactive atmosphere-aerosol forecast system Acknowledge: Development and operational implementation of NGAC represents a successful “research to operations” project sponsored by NASA Applied Science Program, JCSDA and NWS

17 17 Summary and Ongoing Work NGAC model run with QFED2 emissions for 2011 completed Model output will be compared to MODIS AOD to determine scaling factors NGAC model run with GBBEP-Geo emissions for 2011 is currently ongoing QFED code successfully implemented on STAR computers. Other approaches to determine scaling factors (inter-satellite calibration) will be used to minimize the model simulations needed. Product validation is critical. Direct validation is currently not possible because of the lack of reliable in-situ measurements. We will work on inter-comparison with other biomass burning emission products. Algorithm Critical Design Review (CDR) to be held in May 2013
