Statistical and Dynamical Mesoscale Climate Downscaling

Among the fundamental, defining characteristics of any dataset is resolution in space and time.  In atmospheric science, the resolution of output from a numerical model or of an observational dataset determines the threshold for what phenomena can be well characterized from the data (one might say depicted, represented, or resolved) and what phenomena cannot.  Downscaling is a method of objectively inferring information at a higher resolution than a dataset might normally provide, given its native spacing of data in space and/or time.
