Summary
The version of FSCBG (Forest Service Cramer Barry Grim) described in this
technical manual combines and implements mathematical models for aircraft wake effects,
gaussian line source dispersion, droplet evaporation, canopy penetration, and ground and
canopy deposition. FSCBG is designed to account for the atmospheric dispersion,
transport, and deposition of all aerial spray material from the time of release until the spray
material is either deposited or, in the case of spray drift, until the spray concentration and
deposition levels become insignificant. Specific calculations made by FSCBG include
spray concentrations and dosages above and within forest canopies as well as the spray
deposition within and below forest canopies, resulting from aerial spray releases made
along single or multiple flight paths. This document serves as the technical resource
manual for FSCBG.
