Smoke Dispersion Forecast

The forecast shows contoured areas which represent the smoke concentration level relative to the initial emission value. The across-wind thickness of the plume gives an indication of wind speed. The current smoke dispersion forecasts are produced twice daily. After the city based ACCESS-C (Australian Community Climate and Earth-System Simulator) and the Australia wide ACCESS-A models are run, producing data valid for up to 48 hours into the future, HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) smoke dispersion forecasts for each state are created for burns on the following day. The forecasts are currently run from fixed source locations provided by users in each state.
