METI-LIS Version2

Counter

This model was developed for a better simulation of downdraft effect accompanying low emission sources.

The METI-LIS puts special importance to expressing the effect of downdraft when building data around the sources are given, while it gives solutions of simple Gaussian plume and puff formula for elevated sources.

Basic concept of formulation follows that of the ISC model (US-EPA), with improved parameterization after new experiments.
