Essential input data are emission rate and other emission conditions such as location, height, gas volume
and temperature, and meteorological factors at every hour during the averaging period. Users can select an
optional mode of average simulations for either short-term or long-term. For most locations in Japan, the
AMeDAS data supported by the Japan Meteorological Agency (provided in CD every year) are applicable to the
latter case. In the English version, long-term meteorological data file is imported as an external file prepared by
the users.
