Emissions Modeling & Inventory
The Air Division is charged with the responsibility of insuring that Alabama's air quality meets federal standards. The Air Division has several QA/QC methods that can be used in order to analyze the quality of Alabama's air. Computer models use air emissions to simulate what the ground-level concentrations of a pollutant(s) would be using meteorological data and terrain information. Stack tests are conducted to measure the actual levels of emissions that are being released by a facility. Emission inventories use the past year's actual emissions to analyze emission trends.
