| This calculator is a mathematical model of the schematic shown at right. To use this model, provide values for:
- C0: initial concentration (in some units, such as parts per billion) on the upward side of the modeling area
- H: the height of the mixing layer, in units of meters (m)
- L: the length of the modeling area (west to east, in meters)
- Q: the source emission rate of the pollutant (in the same units as initial concentration
- U: the wind speed in units of meters per second
Use this calculator to investigate different scenarios, such as:
- How does the wind speed affect concentration?
- How does a lower mixing height affect concentration?
