HYSPLIT was originally designed to run offline utilizing meteorological data such as are provided by WRF-ARW. A new model framework has been developed that the revised HYSPLIT model is coupled inline with WRF-ARW to take advantage of the higher temporal frequency of the meteorological variables produced by the meteorological model, as well as using WRF-ARW's vertical coordinate scheme. The inline coupling approach is a more consistent depiction of the state of the atmosphere available to the dispersion model through the elimination of the need to interpolate the meteorological fields temporally and vertically. This forum was created to foster discussion on the use of the In-line WRF-HYSPLIT coupling.
