The simulation is close to complete 20 years. I looked at the ocean output with Frank and Gokhan. Lab Sea convection shuts off after a few years and it does not recover. The Lab Sea freezes in winter, but so far it's melting during summer. We suggest stopping the run once it completes 20 years. We will perform a more thorough analysis after the CESM workshop.

ADF diagnostics have been uploaded here.

cecilehannay commented 2 years ago

@PeterHjortLauritzen: I checked that OMEGA500 for the new topo vs old topo is available in the ADF diags.

I confirmed that OMEGA500 is in the ADF LatLon plots.

ADF diag has been updated to include RESTOM variable now.

@JulioTBacmeister I looked at the impact of this no leak run on the GrIS SMB. It doesn't look to be making any appreciable difference:

temp_tseries_GRIS

Note I am incorrectly assigning these 20 year runs to years 1979-1998, even though they are perpetual 1850 runs. Either way, the dark and green lines are so similar that it shouldn't stop us from moving to no leak topo, IMO.

JulioTBacmeister commented 2 years ago

Interesting. Attached are plots of mean TS for years 9-19 of these two runs. Red in the diff plot at the bottom means no-leak topo is warmer. In the annual mean no-leak topo is warmer along the Greenland coast and cooler on the plateau. But this seems to dominated by warmer temps during the cold season (JFM) in no-leak topo. In the 'warm' season (JAS) the coastal warming in no-leak topo is reduced quite a bit, while the cooling of the central plateau is strengthened.

@JulioTBacmeister will provide a slightly modified topo file for the new coupled run.

JulioTBacmeister commented 2 years ago

should be ready later this morning

adamrher commented 2 years ago

I made comparison of the topo used on 007 vs 008 (noleak), along an west and east transect over Greenland:

temp_transect

I like that the summit is higher in BM+noleak, closer to the raw dataset (ncube3000). And the steeper margins in BM+noleak seem to be an improvement as well.

JulioTBacmeister commented 2 years ago

new topo fille is here:

/glade/p/cgd/amp/juliob/bndtopo/latest/ne30pg3_gmted2010_modis_bedmachine_nc3000_Laplace0100_20220622.nc

PHIS is identical to what Adam looked at above, only subgrid quantities are slightly different.

JulioTBacmeister commented 2 years ago

@adamrher I also see no reason not to make the new rescaled 'no-leak' laplacian-smoothed topo the default.

cecilehannay commented 2 years ago

Perfect. I will include the new topo file in the next coupled run.

adamrher commented 2 years ago

@cecilehannay remember that I've pushed changes to my cam6_3_058.dtsens branch about 7 days ago to fix the ice clouds. Can you make sure you are running with these changes? You can check by searching for my initials "ARH" appear in cam_nucleate_ice.F90. If they are there, you have the changes.

cecilehannay commented 2 years ago

HI @adamrher It looks that the tag I am currently using has"ARH" in nucleate_ice_cam.F90and a lot of other places ;) Would you mind confirming this sandbox has all the changes you want: /glade/work/hannay/cesm_tags/cesm3_cam6_3_058_MOM_b/components/cam/src/physics/cam

adamrher commented 2 years ago

looks good!
