At @ECMWF we have routine monitoring plots of the (old) ocean analysis system #ORAS5*.
These are designed by my office mate and ocean expert Eric de Boisseson.

*The new system, #ORAS6, is in place but publishing the equivalent plots is not yet there.

What was a preprint is now fully published: https://tc.copernicus.org/articles/20/3299/2026/
Sea ice data assimilation in #ORAS6
The paper documents our methodology for constraining the sea ice with concentration observations in our new reanalysis and NWP system.
Further papers on the system as a whole, and climate signals from it are planned. -

Just in time to be superseded by #ORAS6

Happy to report the earliest (and final) stream for #ORAS6 has entered production. Just in the spinup period now, but we have some #reanalysis data valid in 1944 already. Now just to be patient until this reaches 1993 where the already produced stream awaits...
