Before revision: The initial version of HYSPLIT (HYSPLIT1) was developed in 1982 and obtained meteorological data solely from rawinsonde measurements and its dispersion calculations assumed uniform daytime mixing and no mixing at night.Draxler, R.R., and A.D. Taylor, 1982: Horizontal dispersion parameters for long-range transport modeling.
