COAPS QuikSCAT 4xDaily Pseudo-Stress Vectors for the Gulf of Mexico

Fields of pseudo-stress are produced using a variational approach (direct minimization) with tuning parameters determined using Generalized Cross-Validation (GCV). These products are on a 0.5x0.5 grid, and are available four times daily (0Z, 6Z, 12Z, and 18Z). The scatterometer winds, and these gridded winds, are calibrated to a height of 10 m. This approach utilizes the only QuikSCAT observations filtered by the NOF rain flag and should be considered as a research quality data set. The technique used to make these fields is based on the method of Pegion, P. J., M. A. Bourassa, D. M. Legler, and J. J. O\'Brien, 2000: Objectively-derived daily "winds" from satellite scatterometer data. Mon. Wea. Rev., 128, 3150-3168.

NetCDF libraries are required to access the data, and can be obtained from UNIDATA.
