IWEDA was designed to address the adverse effects of the environment and climate (i.e. wind, precipitation, storms and temperature) on military operations and weapon systems. IWEDA produced a graphic display of weather impacts on 70 weapon systems, including 16 threat systems. Impacts were displayed graphically on a user interface, called the Weather Effects Matrix (WEM), which color coded the impacts on the system of interest (i.e. green “favorable,” amber “marginal,” and red “unfavorable”). Although intended for the Army, applications were also integrated into the Air Force and Navy systems.
