Objective Analysis Using Modeled Space-Time Covariances: An Evaluation,
Abstract
FROM THE National Severe Storms Laboratory and White Sands Missile Range. The effects of data biases on the analysis model are discussed. Methods for estimating the data covariance as a function of space and time separation are discussed and applied to the data. Objectives analyses of the data are made using modeled space-time covariance functions. A sensitivity analysis indicates that the method is not overly sensitive to errors in the estimated parameters. The performance of the method on real and synthetic mesoscale data is compared to that of equally weighted and unequally weighted averages of neighboring stations which were closest in space and time. Frequency response surfaces of averaging and Eddy's method are compared using the geometry of the White Sands Missile Range Network. (Author)
