In 1990, a simple Lagrangian-based sulfur chemistry module
was developed (Rolph, 1992 and 1993) to be incorporated into the
HYSPLIT 3.0 model. The sulfur module is nonlinear (in hydrogen
peroxide) and includes gas- and aqueous-phase oxidation of sulfur
dioxide (SO2) and dry and wet removal of SO2 and sulfate (SO-)
particles. The current version is identical to the original, except
that it has been incorporated into HYSPLIT 4.6.
