Highest resolution global ocean model?
Can someone please tell me which of the established, open access, global ocean models has the highest resolution? I was about to begin looking at each of the websites to see the resolution of their latest version, when this announcement dropped in my email. I decided to see if someone out there can answer it for me.
I have long felt that for many applications (say for sediment transport, or an oil spill), in which people at present sort of reflexively run a local model nested in some global model, it would make more sense (at least as a first approximation) to just use the global model velocities/temperature/salinity, and then perhaps apply some analytic solutions locally, and maybe superimpose tides from a global tidal model. But in doing so, I would want to use the highest resolution global model.
I also hope to get some opinions from others, maybe even start a conversation.

Cedric, thanks for the info. I just want to add that I was not informed of your reply. It might be good to implement a notification system.

Dear John,
Many thanks for your message.
Indeed, the notification scheme is still being fine-tuned, and this issue has been identified.
Regarding your question, I'm in the process of contacting an expert again.
Many thanks in advance for your patience,

Dear John,
To my knowledge there are mainly two products available in real time at high resolution .
1) Mercator Ocean produces global analyses and forecasts at 1/12° based on NEMO (without tides), which are available from the European Copernicus Marine Service: https://doi.org/10.48670/moi-00016 https://data.marine.copernicus.eu/product/GLOBAL_ANALYSISFORECAST_PHY_001_024/description
As you will see in the documentation a tidal component based on FES is available on the same grid in one of the datasets (the name of the dataset finishes by "merged-uv_PT1H-i")
2) The US NRL&COAPS produce global analyses and forecast at 1/12° using HYCOM (with tides) which can be accessed here:
GOFS 3.1: 41-layer HYCOM + NCODA Global 1/12° Analysis
Both models display very good performance on average, but their caracteristics will differ locally. I would recommend to test several model solutions whenever possible. I guess both the European and US teams will be interested in your feedback or questions within this discussion stream!
Kind regards,
Marie
