Site-specific metfiles are usually demanded for near source modelling with area or volume based sources. CALPUFF is an advanced non-steady-state meteorological and air quality modeling system developed by scientists at Exponent, Inc. What would be the length of your metfile? Is one year long metfile sufficient ? What type of metfile do you require? Site-Representative, Site-Specific? Net Radiation where there is no representative cloud dataīoM Synoptic data at the nearest station and Vertical Temperature and Moisture profiles to calculate convective mixing height Total Solar Radiation (TSR) and Cloud cover (source from BoM) to determine Stability classes following the approved methods

modifying vegetation and soil type to match with areas/locations in question.

With high resolution topography (9 second DEM) The pollutant dispersion modelling carried out in the present assessment utilises the Ausplume Gaussian Plume Dispersion Model software developed by EPA. In 5 nested grids, inner most grid with 300m resolution for most cases We can help you to compile input meteorological data files running TAPM V4 Locations supplimentarywhere there are no real observed data we use model generated mandatory data with BoM’s off-site data to compile metfiles.ĬSIRO’s The Air Pollution Model (TAPM, Hurley et.al, 2005) is the most frequently used model for this purpose. New South Wales accepts a number of models including: AUSPLUME.

Model generated data (TAPM,CALMET,MM5,WRF)īoM’s supplementary data such as Pressure, Dew point Temperature, Cloud Cover as well as Vertical Temperature and Moisture profiles are used with above mandatory data to compile 100% AUSPLUME V6 compatible metfiles. Air pollution modelling is often used to identify key negative impacts the facility may.

State EPA’s hourly averaged mandatory data (Winds, Temperature and Sigmatheta)Īustralian Bureau of Meteorology (BoM) 1minute/10minute/1 hour average data Sourcing of mandatory raw data is done following the recommended hierarchy by EPA,Victoria This methodology is widely accepted, all regulatory bodies (all state EPAs and overseas agencies) accept this methodology. AUSPLUME We compile AUSPLUME type input meteorological data files strictly following EPA,Victoria’s guidelines.
