CM3 dev evaluation meetings.
Next Tuesday there is an open CM3 dev evaluation meeting at 10:30am
This could be of interest to a broader COSIMA community. Action: @cbull to advertise this to COSIMA community
IAF beta release
@ezhilsabareesh8 is release coordinator for IAF 25k beta release. The purpose of this release is to give the experiment a human-readable name and makes it easier to align with other models such as CM3. There are plans to do a short test run before a release and after some bathymetry changes. There is a list of priorities on the project board (PO is priority, P1 is nice to have). Aiming to release in about 2 weeks.
Main changes for this release are an updated executable and bathymetry modification
OM3 evaluations
Hovmoller plots show funny temperatures in the vertical (at ~500 m). This is probably due to diffusivity from not parameterising the internal tides quite right. @aekiss and @AndyHoggANU to investigate further
The Indonesian throughflow has flows going through the wrong channels. Probably a bathymetry issue which was also present in OM2. @aekiss and @AndyHoggANU to formally raise this issue via the release project board. UPDATE: @aekiss created an issue.
@cbull has recently run all the OM3 evaluations on makefigs but half didn’t work. Most errors can be accounted for by a grid error that will be fixed in future runs. However, these evaluations will be needed over the next 2 weeks. @aekiss and @cbull to discuss next week.
Sulu sea
There is a channel in this region that is open but not by much. However, there is not a large resovear of water building up so happy to leave as is.
Discussion on potential future experiment runs
These are:
-
There will probably be a CM3 100km run and an OM3 100k IAF could be run for comparison
-
Sensitivity runs on mixing/subsurface temperature issues
Some of the planned future releases that may also need control experiment runs:
-
25 km config for upcoming release
-
8km config for future alpha release
-
Panantarctic domain for future alpha release.
