COPTER - EOSAEL Module

COPTER models the obscuration produced by helicopter-lofted snow and dust. It is based on a combination of helicopter-downwash models and models of obscuration by blowing snow. The module treats the cases of a helicopter crossing a specified line of sight, hovering near the LOS, or lying parallel to the LOS. The resulting broadband transmission versus time is scaled from the visible to mid-infrared, far-infrared or millimeter wave bands. The helicopter type, speed, path, and surface conditions may be varied. The case of helicopter-lofted dust is also treated, using models of obscuration by blowing dust. Model output can be as simple as minimum transmission and time periods when transmission is less than 5 percent or as detailed as text plots for all wave bands.
