What Actually Happened
List of papers that was presented at the May 2015 meeting:
- Expect to use last 30 min for discussions with Chris Golaz on how to best support coupled model with alpha9 / alpha10 / beta1 (discuss process)
- Mathew Maltrud discussed eddy closure 60to30 runs for low-res water cycle / BGC (/wiki/spaces/OCNICE/pages/102039847)
- ocean-ice core circulations having trouble to have robust meridional overturning circulation (MOC) without salinity restoring
- some improvement with salinity restoring, but additional strength of restoring may be required as demonstrated from RAPID array
- increase in piston velocity reduces drift in salinity
- note, no ocean model in world that doesn't require salinity restoring (e.g., precipitation independent of ocean model without feedback); debate continues over use of restoring timescale
- sea surface temperature drift is minimal, no restoring needed for sst
- minimal cost at higher resolution (1440 cores on eos, 6 SYD)
- BGC version only run for 1 yr, can couple 1 to 2 way with sea ice BGC to add 3-4 cost in individual components above physics-only configuration. Configurations current in testing by Shanlin Wang (Unlicensed) with Keith Moore et al
- MARBL SciDac project with NCAR with Matt Long for v2
- Hard to get anything higher resolution than 60to30 through queue at reasonable SYD because of queue times and node failures
- 16to5 and 18to6 have gone through a few times at 64k processors
- David C. Bader: "don't submit additional jobs on titan (beside Mathew Maltrud and Jon Wolfe)"
- Milena Veneziani: Analysis discussion (milenaMPASAnalysis_Nov2016.pdf) is a continuation of Kate Evans (Unlicensed)' earlier discussion
- MPAS Analysis Members (AMs) performs analysis online, MPAS-Analysis produces plots from MPAS AMs; all must be in sync with ACME
- MPAS-Analysis is submodule of ACME analysis workflow
- MPAS-Ocean has test cases (independent of global ocean) and analysis of global ocean is contained in ACME workflow
- Prioritization of ACME coupled diagnostics
- Chris Golaz: consider adding more diagnostics for a more complete suite, e.g., add plot of RMS error, plot of sea surface salinity, trends of temp / salinity anomalies
- https://github.com/MPAS-Dev/geometric_features: defines ocean regions, southern plains ARM site, Indian monsoon region, etc. (model independent but applied to specific model)
