An introduction to aerial spray modeling with FSCBG. Forest Service Cramer-Barry-Grim

The FSCBG aerial spray drift and deposition model predicts the dispersion of material released from aircraft into the atmosphere, and particularly downwind from the release point. The effects of aircraft wake structure, droplet evaporation, local meteorology, penetration through forest or agricultural canopies, and prediction of ground or canopy deposition, air dosage, and concentration are all included in the model. The long developmental and validation history of the model, a brief summary of its assumptions and underlying approximations, and its present user-friendly operation on personal computers are reviewed and highlighted in this paper.
