Navy's GOFS 3.1 Analysis Reaching End of Life

[Michael McDonald]

The Navy's GOFS 3.1 Analysis runs every day, but the computer it uses is due to be decommissioned on Friday 07 June 2024 so the last GOFS 3.1 Analysis will likely be on 06 June.

It is being replaced by the Navy's ESPC system, see:

The Navy's Earth System Prediction Capability: A New Global Coupled Atmosphere-Ocean-Sea Ice Prediction System Designed for Daily to Subseasonal Forecasting

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020EA001199

This consists of a 1/12-degree 16-member ensemble system run weekly and a 1/25-degree deterministic system run daily. We will be serving the daily deterministic analysis and forecast, but on the existing GLBy0.08 (1/12 degree) grid. We hope to have this ready to go before GOFS 3.1 is turned off.

HYCOM Users:

The Navy's GOFS 3.1 Analysis was finally decommissioned on Sept 4, 2024 and the final switch was made to the ESPC outputs. We just received word of this late on Friday evening (yesterday), so hycom.org is still receiving that new data and configuring THREDDS for aggregated access. We hope to have this operational early next week. 

In the meantime, you can see/access the unaggregated data files here once we make these public,
