Abstract: Quantitative approaches to the evaluation of model performance were recently examined by Fox (1981). His recommendations are briefly reviewed and a revised set of performance statistics is proposed. It is suggested that ...

Abstract: Two ?smart? interpolation procedures are presented and assessed with respect to their ability to estimate annual-average air temperatures at unsampled points in space from available station averages. Smart approaches ...

Abstract: January and July surface air temperature fields simulated by the GFDI, OSU, GISS, and UKMO general circulation models (GCMS) are compared to the global surface air temperature climatology compiled by Legates and Willmott. ...

Abstract: Water balance calculations are becoming increasingly important for earth-system studies. Precipitation is one of the most critical input variables for such calculations because it is the immediate source of water for the ...
