4435bfa Merge remote-tracking branch 'rgknoxfork/rgknox/lnd/fates-conditional-timesteps'(PR #4884) This is a simple fix to prevent FATES code that handles some time keeping routines, from being called when FATES is not active.

8aef31a Merge branch 'mark-petersen/ocean/eddy-length-limiter-visbeck' (PR #4868) Limit Visbeck eddy length to dcEdge When using config_GM_closure='Visbeck' (Visbeck et al 1997), limit the eddy length scale to be no less than dcEdge, the distance between cells. This ensures that gmBolusKappa does not have very small values due to the eddyLength factor. When using config_GM_closure='Visbeck' it is not BFB. However, all E3SM runs use config_GM_closure='constant' or 'EdenGreatbatch', but never Visbeck, so this PR is BFB for all current tests. [BFB] 14 April 2022, 19:10:21 UTC

48ff595 Merge branch 'benedict/atm/ssp370_ssp585' (PR #4844) Add and update SSP370 and SSP585 Added SSP370 compset "WCYCLSSP370" and updated existing compset "WCYCLSSP585". For SSP370, the new "WCYCLSSP370" compset was defined, new EAM and ELM use case files were created, new prescribed forcing files were created, and minor changes elsewhere were added by emulating what was done for SSP585. For the updated SSP585, the "WCYCLSSP585" compset was defined, new land use and land cover change files were created (these files are grid-specific, and the default atm_lnd grid changed from v1 to v2), and the ELM use case file was updated to point to these new files. The atmosphere forcing files set in the SSP585 use case were not changed because they are not grid specific and they already existed from v1. All SSP370 EAM and ELM input files were staged in NERSC-Cori's inputdata directory only. [BFB] for tests not using SSP370 or SSP585 12 April 2022, 15:00:31 UTC

565da94 Merge branch 'mark-petersen/ocn/gm-min-phase-speed' (PR #4835) Add choice of computed or constant ocean GM gravity wave speed Currently the internal gravity wave speed (first baroclinic mode) in the ocean GM parameterization is a constant, previously named config_GM_constant_gravWaveSpeed but changed in this PR to config_GM_constant_bclModeSpeed. This remains the default, but this PR adds a new flag, config_GM_minBclModeSpeed_method: If 'constant' (the default) then use config_GM_constant_bclModeSpeed. If 'computed' then compute the gravity wave speed at every edge at every time step using the Brunt-Vaisala frequency.

f04c320 Merge branch 'cbegeman/ocn/add-explicit-layerThickEdge-vars' (PR #4832) Add explicit layerThicknessEdge variables This PR replaces the existing layerThicknessEdge variable with two variables: * layerThicknessEdgeMean refers to the mean of the neighboring cell-centered layerThickness * layerThicknessEdgeFlux refers to the layerThicknessEdge used to flux momentum and tracers. When config_thickness_flux_type = 'centered' layerThicknessEdgeFlux = layerThicknessEdgeMean, but when config_thickness_flux_type = 'upwind' layerThicknessEdgeFlux is upwinded. Prior to this PR, when config_thickness_flux_type = 'upwind' layerThicknessEdge was upwinded everywhere. This PR uses layerThicknessEdgeFlux for horizontal advection terms and layerThicknessEdgeMean elsewhere, such as for mixing parameterizations. This change is in preparation for adding additional options for thickness fluxes. This PR also removes layerThicknessEdge from global stats, since it did not offer much information not given by the global stats for layerThickness. [BFB] 31 March 2022, 14:49:04 UTC
