Highlights

Summarizes the historical development of the AGDISP/AGDISPpro deposition model.

Provides details implementing the modeling of crosswind effects on aircraft vortices.

Examines model agreement for two datasets: in-wind and crosswind fixed-wing aircraft deposition and hovering/rotating UAV spot spraying deposition.

Interprets CHARM model predictions for maximum UAV forward flight wake decay times.

Abstract. This article describes recent AGDISPpro model comparisons, addressing the separate upwind-downwind decay of aircraft vortices because of crosswind effects, model comparisons with in-wind and crosswind field data and UAV spot spraying data, and model predictions of UAV forward flight wake decay times. These data comparisons extend AGDISPpro usage to additional agricultural spraying applications and to UAV model development beyond the agricultural spraying to which AGDISPpro was historically developed.
