CALMET

DESCRIPTION

CALMET is a diagnostic meteorological model able to construct, by means of available meteorological observations in some points, the wind field and the boundary layer structure over water and over land in the whole calculation domain.

The diagnostic wind field module uses a two steps approach. In the first step a first guess wind field is adjusted for kinematics effects of terrain, slope flows and terrain blocking effects. The wind field obtained in this way is then modified according to the observational data to produce a final wind field. In this second step an inverse distance squared interpolation scheme is used to weight the observed data heavily close to the observational station, while in regions where no measurements are available the wind obtained during the first step dominates. The vertical wind is then calculated by means of a divergence minimisation procedure.

The Earth Tec site above describes the model operation, input, output, and applications.
