Design Criteria and Eigensequence Plots for Satellite-Computed Tomography
Publisher: American Meteorological Society
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 ...
Some New Mathematical Methods for Variational Objective Analysis Using Splines and Cross Validation
Publisher: American Meteorological Society
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 ...
Cloud Classification of Satellite Radiance Data by Multicategory Support Vector Machines
Publisher: American Meteorological Society
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. ...

Spatial–Temporal Analysis of Temperature Using Smoothing Spline ANOVA
Publisher: American Meteorological Society
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 ...
Partial Spline Models for the Inclusion of Tropopause and Frontal Boundary Information in Otherwise Smooth Two- and Three-Dimensional Objective Analysis
Publisher: American Meteorological Society
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 ...
Adaptive Tuning of Numerical Weather Prediction Models: Simultaneous Estimation of Weighting, Smoothing, and Physical Parameters
Publisher: American Meteorological Society
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 ...
Adaptive Tuning of Numerical Weather Prediction Models: Randomized GCV in Three- and Four-Dimensional Data Assimilation
Publisher: American Meteorological Society
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 ...
