Show moreSpatialVx is a software package written in R for performing spatial weather forecast verification primarily on gridded verification sets (i.e., a gridded observation field com-pared against a forecast field on the same grid). In a more general sense, sptial verification is all about comparing spatial fields and has a broader application area, such as compar-ing photographic images; though unique challenges in the realm of forecast verification exist. Background on spatial verification methods is given along with a tutorial for the key functions of the package. Beyond a description of the software, a look at some of the many challenges associated with spatial verification is explored and key areas for further statistical development are highlighted.
