Sažetak
The ADMS range of models (ADMS4 for industrial emissions, ADMS-Screen, ADMS-Urban and ADMS-Roads) are
currently used across the world and have been widely used in Asia, e.g. Mainland China, Hong Kong, and India. This paper
considers the regulatory requirements for dispersion modelling and the application of ADMS in Taiwan. Until recently ISCPrime
has been the only short range dispersion model acceptable for regulatory purposes in Taiwan. For the purposes of regulatory
dispersion modelling, Taiwan is divided into 16 different regions each region containing a significant urban area; for example there
are areas centred on the major cities of Taipei and Kaoshung. Each region has assigned to it a particular representative
meteorological dataset (hourly data for a full year) and surface conditions including surface roughness; because of the mountainous
nature of Taiwan the impact of complex terrain needs to be considered in all cases. Previously as part of the regulatory requirements
modelling test cases for single point sources were set up with ISCPrime for each of the regions and these datasets are available on
the Taiwanese EPA website. In order for ADMS to be approved for use in Taiwan the test cases were required to be run for ADMS.
Model output required included contour maps of the annual 1 h mean concentration, and 1 hour and 24 hour average percentiles and
a time series of 24 hour averages at specified receptor points time. This paper presents the results of using those datasets for ADMS
4, and discusses the performances of ADMS in a Taiwan context including where appropriate comparison with ISCPrime and
discussion of the impacts of complex terrain and surface roughness in the different regions.
