emissions inventory
Emissions Inventory
  • Fall Line Air Quality Study [August 11-20 2000]
    • Meteorological data
    • Emissions Data (EDMS 4.01)
  • PM2.5 Estimation (Method1)
    • General Aviation, Air Taxi, Military Aviation =>EF from EPA (ERG, 2003)
    • Commercial Air Aviation => Ratio wrt. Air Taxi VOC
