Daily Antarctic Sea Ice Forecast
« on: July 22, 2014, 04:27:45 PM »
NRL has a new global ocean and sea ice forecasting system, which is on track to become a US Navy operational product.  It is similar to the Arctic Cap Nowcast/Forecast System (ACNFS), but with improvements and extended to the entire globe.  So far as I know, it is the first forecast system for Antarctic sea ice.  There is currently only a 3 day forecast, but it will be 7 days (like ACNFS) eventually.  See http://www7320.nrlssc.navy.mil/GLBhycomcice1-12/skill.html

Another difference from ACNFS is that there will be actual model data fields served from hycom.org.  These are not available yet. 

The best place to ask about this system, or report issues, is at the hycom.org forum reachable from HYCOM's home page.

Thanks for the heads up Alan.

It's intriguing that the GLB Arctic sea ice thickness currently look very different to the ACNFS version!

Jim: The Global system's Arctic total sea ice volume is closer than ACNFS's to that from PIOMAS.  Compared to IceBridge's 2013 Arctic campaign, Global ice thickness is closer to the observed flight data in the regions of the Beaufort Sea and Canadian Archipelago whereas ACNFS has lower error for the region north of Greenland.
