attribute NC_GLOBAL acknowledgement String The gridded data were generated from the multiple satellite observations of DOD, NOAA and NASA (and future others) and wind retrievals of the Remote Sensing Systems, Inc. (, using scientific methods such as objective analysis (OA). The OA is only truly objective when the needed statistics are completely known, which may not always be the case. The ERA-5 wind directions and stresses were downloaded from the Copernicus Climate Change Service (C3S) Climate Data Store
