COAPS NSCAT Global Daily Pseudo-Stress vectors using Variational Method with Generalized Cross Validation


Daily 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 1x1-deg grid. The scatterometer winds, and these gridded winds, are calibrated to a height of 10 m. This approach utilizes the NSCAT overpasses as well as our weighted 8-day fields, and should be considered as an improved (research quality) data set.

A manuscript is in preparation describing these data.


From this interface, you can download individual files, files grouped by month, or the entire collection of gridded NSCAT data produced here at COAPS.

These files are in NetCDF format, which can be obtained from UNIDATA.
