VALLEY: Multiple Point and Area-Source Gaussian Plume Dispersion Model

DESCRIPTION

VALLEY is an air pollution model specifically designed for the complex terrain conditions normally encountered in mountainous areas. It can consider multiple point or area sources and works over a 24 hours o a year period. It requires a stable, unstable or neutral atmosphere to suitably correct the plume height taking into account the terrain elevation.
