This method attempts to retain the high spatial resolution of the scatterometer where there are adequate measurements. To estimate the covariance function and to compute realistic error estimates for the method, a synthetic data set was constructed using wind fields from the European Centre for Medium Range Weather Forecasts. The wave number spectrum of the synthetic data was based on an analysis of Seasat scatterometer data. The patchiness of the scatterometer data caused discontinuities in the objective estimates, which would give unacceptable wind stress curl field; thus the initial estimates were selectively smoothed using overdetermined biharmonic splines. A constraint on the horizontal divergence of the wind, applied only in regions of large estimated errors, improved the estimates. -from Authors
