Release Height and Far-Field Limits of Lagrangian Aerial Spray Models
2003
Teske, M.E. | Thistle, H.W.
The Lagrangian equation solver in the aerial application models AGDISP (version 8.08) and AgDRIFT (version 2.0.08) is capable of predicting deposition from high release heights and to distances far downwind, beyond where these models have been validated. The appropriateness and applicability of model extension to higher release heights and to farther downwind distances are examined by examining model inputs, model uncertainty, and data variability as these limits are approached. The models appear appropriate as long as the aircraft vortices influence the behavior of the released spray material. While the models have been validated to release heights of 10 m and downwind distances of 800 m, release height extension appears warranted, whereas downwind deposition extension does not. However, relative deposition effects may be examined further downwind.
