In-line WRF-HYSPLIT coupling recent versions

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.

In-line WRF-HYSPLIT coupling recent versions

Post by maiacalvelloWRF »

Hello!
I'd like to ask what are the most recent versions of Hysplit and WRF that can be used for the in-line coupling at the moment.
Thanks
Maia

The inline HYSPLIT coupled with WRF uses the HYSPLIT code prior to v5.0.0 (https://www.arl.noaa.gov/hysplit/hysplit-model-updates/). It is HYSPLIT revision 700-800. All the revisions up to v4.2.0 are relatively minor in terms of the coupling approach. However, we have major updates and changes starting v5.0.0. The inline HYSPLIT was updated with the more recent WRF version (up to v4.2.2) but not with the recently updated HYSPLIT.
