A1.2 TAPM meteorological modelling configuration

TAPM (The Air Pollution Model) was developed by the CSIRO and has been validated by the CSIRO, Katestone
and others for many locations in Australia, in south-east Asia and in North America (CSIRO, 2008). Katestone has
extensive experience with TAPM for sites throughout Australia and in parts of America, Bangladesh, New
Caledonia and Vietnam. The model performs well in simulating regional wind patterns and has proven to be a
useful tool for simulating meteorology in locations where monitoring data providing the vertical distribution of
meteorological parameters are unavailable.

TAPM is a prognostic meteorological model which predicts the flows important to regional and local scale
meteorology, such as sea breezes and terrain-induced flows from the larger-scale meteorology provided by the
synoptic analyses. TAPM solves the fundamental fluid dynamics equations to predict meteorology at a mesoscale
(20 km to 200 km) and at a local scale (down to a few hundred metres). TAPM includes parameterisations for
cloud/rain micro-physical processes, urban/vegetation canopy, soil type and radiative fluxes.

TAPM requires synoptic meteorological information for the region. This information is generated by a global model
similar to the large-scale models used to forecast the weather. The data were supplied on a grid resolution of
approximately 75km, and at elevations of 100m to 5km above the ground. TAPM uses this synoptic information,
along with specific details of the location such as surrounding terrain, land-use, soil moisture content and soil type
to simulate the meteorology of a region as well as at a specific location.

TAPM version 4.0.5 was configured with the following parameters:

    •    Modelling period from 1 January 2020 to 31 December 2020

    •    48 x 48 grid point domain with nesting resolutions of 30 km, 10 km, 3 km, 1 km, and 300 m

    •    25 vertical levels

    •    Grid centred on latitude -26° 26.5’, longitude 153° 1.5’
