Abstract: Cross-validation is a statistical procedure that produces an estimate of forecast skill which is less biased than the usual hindcast skill estimates. The cross-validation method systematically deletes one or more cases in ...

Abstract: Frequency domain principal components analysis, a technique which involves extracting the eigenvalues and eigenvectors of the cross spectrum of a multivariate time series, is used to analyze the development and movement ...

Abstract: Tree-ring chronologies have been used to develop a 400-yr spatial reconstruction of precipitation in coastal and near-interior southern California. This was accomplished by reconstructing the first two precipitation principal ...

Abstract: An extension of Sinclair's diagnostic model of orographic precipitation (?VDEL?) is developed for use in data-poor regions to enhance rainfall estimates. This extension (VDELB) combines a 2D linearized internal gravity ...

Abstract: Long precipitation reconstructions (600 years) developed for Santa Barbara, California, using new big-cone spruce tree-ring chronologies capture over 55% of the annual precipitation variance. The modern period of the ...

Abstract: Some of the most widely used datasets for monitoring the world?s fires come from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors aboard NASA?s Terra and Aqua satellites. For virtually all remote sensing ...

Abstract: In the early 1900s, tree-ring scientists began analyzing the relative widths of annual growth rings preserved in the cross sections of trees to infer past climate variations. Now, many ring-width index (RWI) chronologies, ...

Abstract: AbstractUnderstanding the dynamics and physics of climate extremes will be a critical challenge for twenty-first-century climate science. Increasing temperatures and saturation vapor pressures may exacerbate heat waves, ...
