%description
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.
