Spray deposition dispersion model

The FSCBG aerial spray computer program is the result of more than a decade of refinement and verification of spray dispersion models used by the USDA Forest Service and the U. S. Army for predicting the drift, deposition and canopy penetration of particles and drops downwind from aircraft releases. This paper describes the mathematical framework of the models and selected applications of the models to military and Forest Service projects. 

In summary, we now have models that account for all important forces influencing the dispersion and deposit of aerial sprays. We have estimates of inputs to make the models useful to forest managers. Further improvement in model results, particularly drift estimation, depends on better meteorological input.
