ASCAT ON METOP-A LEVEL 4 DAILY GRIDDED MEAN WIND FIELDS IN 0.25° GEOGRAPHICAL GRID

Purpose

These daily wind and wind stress fields have been estimated over global oceans from Metop/ASCAT retrievals using objective method. The analyses use standard products ASCAT L2b during the period April 2007 through March 2009, and ASCAT L2b 12.5 from April 2009 to present. The resulting fields have spatial
