Both AEROPLUME and HFPLUME give a near-field description of steady-state pressurised releases for either a non-reactive multi-compound two-phase aerosol release (AEROPLUME) or a release of an HF/water/inert gas mixture (HFPLUME).

A unique feature of the models is that they can describe the transition from a fully airborne plume via a touchdown phase to a grounded (heavier-than-air) cloud of pollutant in one, fully integrated formulation.

Both AEROPLUME and HFPLUME also contain a reservoir/discharge model, which acts as a description of the pollutant release conditions.

AEROPLUME replaces the PLUME model.
To run AEROPLUME chemical information relevant to the system of interest should be incorporated into the DATAPROP data base.
