Hi all, As promised, I’ve tried to compile some relevant details for ocean and ice model development in ACCESS-ESM1.6. I’m sure things will be missing or unclear so please send questions to Anton or Aidan (particularly for Spack questions). Please also feel free to contact me, though I’ll be on le…

updated ocean time series plots for the 3 current test simulations. [Octtest_spinup_ocean_temperature_5] [Octtest_spinup_ocean_salinity_5] [Octtest_spinup_SST_5] [Octtest_spinup_SSS_5]

A small number of global time series from the atmosphere - blue is the previous long spin up (Dec-April-June-August, concatenated), orange is test-B (Sept and Oct phases). [Octtest_spinup_tas_5] [Octtest_spinup_precip_5] Top of atmosphere energy balance - noting that we suspect the “steady-stat…

and finally, global metrics for the main land carbon fluxes - note that around year 1280 (dotted line) a bug fix was introduced to the test-B spin up. [Octtest_spinup_NBP_5] [Octtest_spinup_GPP_5] [Octtest_spinup_NPP_5] [Octtest_spinup_R_soil_5]

We might have been worrying too much about the deep ocean and not enough about 1000 m. This is a comparison of the last 100 years of Oct-B, 0101-0200 of the ESM1.5 piControl and World Ocean Atlas. Overall I don’t think 1.6 is worse than 1.5 (though not a very high hurdle in this case) [layer_diffs…

Hi @MartinDix Thanks for all your plots, I am not entirely surprised that the surface layers may be cooler than ESM1.5, we have had the solar constant cooling change impact and you had a mean SST difference of 0.35 C between the ESM1.5 and OctB run. In OctB the region at 1000m depth is a combinat…

Latitude-depth plots were wrong (thanks to @manodeep for noticing something suspicious). Corrected version [ocean_zonal_temp]

Here are the meeting minutes today Please fill in my missing/misunderstanding bits. Particularly given I missed the first five minutes.

Minutes for today’s stand up . Please edit/amend for any corrections

@matthew.chamberlain has just written a topic to enable outputs to calculate meridional ocean tracer transport. Do we want to put in these changes in our next spinup run? If so, do we want these additional diagnostics to be always output or only for a short time period? I am conscious that more dia…

I’ve realised during the meeting that since Chris was on leave, he wouldn’t be taking notes.

I’ve put together some notes as best I could. Please edit/amend as necessary.
