sad - Verify the Scale, Anisotropy and Direction of Weather Forecasts
Implementation of the wavelet-based spatial verification
method of Buschow and Friederichs "SAD: Verifying the Scale,
Anisotropy and Direction of precipitation forecasts" (2020,
submitted to QJRMS). Forecasts and Observations are transformed
by a decimated or redundant dual-tree complex wavelet transform
to analyze the spatial scale, degree of anisotropy and
preferred direction in each field. These structural attributes
are compared by a series of scores. An experimental algorithm
for the correction of these errors is included as well.
