5 Overall Goal Emissions inventory Air quality model input
Usually annual data (i.e. tons/yr) Reported by source (may be county or coordinate) By inventory pollutant (CO, NOx, VOC,,,) Air quality model input Hourly Gridded By model species May be 3-D file (layered) ©2011 Institute for the Environment

6 Source Categories Point source characteristics
Country, state, and county (FIPS) Latitude and longitude Plant, point, stack, segment, and source category code (SCC) Ex: power plants, furniture refinishers Area source characteristics Country, state, and county Source category code (SCC) Ex: residential heating, lawnmowers, vehicular road dust (unpaved road),airports. ©2011 Institute for the Environment

7 Source Categories Mobile (on-road) source characteristics
Country, state, and county Road type (e.g. rural interstate, urban local) Vehicle type (e.g. light/heavy duty gasoline vehicles) Optional link coordinates ( road segment within a county) Ex: gasoline and diesel vehicles on freeways Biogenic source characteristics Gridded land use Ex: crops, corn, soybean, conifer forests, wetlands ©2011 Institute for the Environment

8 Definitions Inventory pollutant: A compound or group of compounds defined for record-keeping and regulatory purposes (e.g. CO, NOx, VOC, PM10, PM2.5) Species: A compound or group of compounds defined as part of the estimation of air chemistry in an air quality model (AQM) (e.g. CO, NO, NO2, PAR, TOL, OLE) ©2011 Institute for the Environment

9 Definitions Speciation: Convert the inventory pollutant data to the species needed by the AQM (e.g. VOC gets split into PAR, OLE, XYL, TOL, ISOP, and more) Chemical mechanism: A parameterized representation of coupled chemical reactions (e.g. CB4, RADM2, SAPRAC99, CB05) ©2011 Institute for the Environment

10 Definitions Map projection: The mathematical 2-d representation of the spherical surface of the Earth (Emission and Air Quality Models shares) Model grid: A 2-d region based on a map projection; defined by starting coordinates, number of columns and rows, and the physical size of the grid cells ©2011 Institute for the Environment

13 Definitions Spatial allocation: Convert the source spatial extent to the grid cell resolution needed by the air quality model Gridding surrogates: A dataset used to spatially allocate the emissions to the grid cells; developed from data at a finer resolution than the emissions (e.g. population, housing, airports, roads) ©2011 Institute for the Environment

14 Definitions Model layers: Vertical spatial divisions of the atmosphere defined by an air quality model; used to model variations in the atmosphere at different vertical positions Plume rise: The rising of exhaust from point sources due to the velocity and temperature of the exhaust gases ©2011 Institute for the Environment

105 Common Problems (3) Problem: Program is ending because an input file is not available Solution: Check the log file to find the name and location of the input file Ensure that the logical file name is defined in the Assigns file or scripts Check that the directory and file name of the input file is correct If the input file is generated by another program, make sure that program completed successfully ©2011 Institute for the Environment
