Abstract: The use of the ?degrees of freedom for signal? is proposed as a design criteria for comparing different designs for satellite and other measuring systems. It is also proposed that certain eigensequence plots be examined ...

Abstract: Let Φ(x,y,p,t) be a meteorological field of interest, say, height, temperature, a component of the wind field, etc. We suppose that data concerning the field of the form ΦI = LiΦ + ?i are where each Li is an arbitrary ...

Abstract: Two-category support vector machines (SVMs) have become very popular in the machine learning community for classification problems and have recently been shown to have good optimality properties for classification purposes. ...

Abstract: A new method, smoothing spline ANOVA, for combining station records of surface air temperature to get the estimates of regional averages as well as gridpoint values is proposed. This method is closely related to the optimal ...

Abstract: A new method, based on partial splint models, is developed for including specified discontinuities in otherwise smooth two- and three-dimensional objective analyses. The method is appropriate for including tropopause height ...

Abstract: In Wahba et al. it was shown how the randomized trace method could be used to adaptively tune numerical weather prediction models via generalized cross validation (GCV) and related methods. In this paper a ?toy? four-dimensional ...

Abstract: In variational data assimilation, optimal ingestion of the observational data, and optimal use of prior physical and statistical information involve the choice of numerous weighting, smoothing, and tuning parameters that ...
