6.3.2.2. Ocean High

 

The Ocean High layer also provides wave, wind, pressure and precipitation data but now at a higher resolution of 0.1 to 0.2 degrees. We switch to the high resolution version of the Great Lakes model, use the NDFD and RAP/HRRR models around the US, Caribbean and Hawai and the Multi_Global source elsewhere. Globally, the latter model provides resolution at 0.2 to 0.25 in this Ocean High deployment as to the 1 degree global resolution presented in the Ocean Fast data.

 

As would be expected with higher resolution data, file sizes and download durations increase when you decide to use these data instead of those associated with the Ocean Fast. Expect size and download times to be 3 to 4x larger than when downloading the same region using Ocean Fast data.

 

Data is available for forecast periods of from 1 to 7 days. Data is updated 4 times each day at approximately 5, 11, 17 and 23 UTC.
