3 Air Resource Management VSMOKE-GIS Simple Gaussian screening model developed by USDA Forest ServiceSimple Gaussian screening model developed by USDA Forest Service Used to determine what impact particulate matter emissions may have on highway visibility and people's health in flat to rolling terrainUsed to determine what impact particulate matter emissions may have on highway visibility and people's health in flat to rolling terrain Interfaces with the Forest Emissions Production Simulator (FEPS) to provide hourly estimates of PM2.5 and heat release rates from a fireInterfaces with the Forest Emissions Production Simulator (FEPS) to provide hourly estimates of PM2.5 and heat release rates from a fire Uses ArcGIS software for spatial inputs and to display the model outputUses ArcGIS software for spatial inputs and to display the model output Available for download from:Available for download from: –http://webcam.srs.fs.fed.us/vsmoke/

5 Air Resource Management PB-Piedmont Model Fine scale time-dependent model for predicting the nocturnal movement of smoke from prescribed burns over rolling terrain typical of that of the Midwest and the SouthFine scale time-dependent model for predicting the nocturnal movement of smoke from prescribed burns over rolling terrain typical of that of the Midwest and the South Purpose:Purpose: –Pre-burn decision-making: If I burn tomorrow, will I smoke up a road tomorrow night? –Post-burn decision-making: Now that I have burned today, where is the smoke most likely going tonight? Provides graphical display of the location of smoke particles on an hour-by- hour basisProvides graphical display of the location of smoke particles on an hour-by- hour basis Can be useful for evaluating “exceptional events” where smoke from nearby fires is thought to be a contributorCan be useful for evaluating “exceptional events” where smoke from nearby fires is thought to be a contributor Additional information available at:Additional information available at: –http://shrmc.ggy.uga.edu/smoke/pb-piedmont/index.html

Layout one or more burn units and ArcGIS calculates information needed for area source file.Layout one or more burn units and ArcGIS calculates information needed for area source file. Display results for all time steps for meteorological data and predicted concentrations (AQI color coded) and visibility.Display results for all time steps for meteorological data and predicted concentrations (AQI color coded) and visibility. n = 8004 receptors

10 Air Resource Management Meteorological Data (PRTMet) Wind speed and direction at 1500 m A.G.L. at 11:00 AM local time.

11 Air Resource Management Start Building the Input Files ArcMap results

12 Air Resource Management FEPS2BAEM ArcMap ® and Fire Emission Production Simulator (FEPS) results are joined together.ArcMap ® and Fire Emission Production Simulator (FEPS) results are joined together. The location of the smoke emissions are moved at hourly intervals.The location of the smoke emissions are moved at hourly intervals. ArcMap results Can have multiple burn units

13 Air Resource Management Finalizing Building the Input Files Tool is being developed to select days meeting certain meteorological criteria. Determine the meteorological files to used in the analysis. Select the quarterly IMPROVE data.
