Complex terrain dispersion modelling exercise
In the framework of the Fourth Workshop, a model inter-comparison exercise is proposed with respect to environmental impact assessment. The purpose of the exercise is to study the compatibility of the performance of similar dispersion models over complex topographies. Contributors were asked to use the same meteorological input over complex terrain topography and to perform dispersion calculations in the surroundings of a small power plant located at the foot of a 1426 m high mountain. A statistical analysis based on the bootstrap method is employed to yield the bounds of a compatible result.
