FunBug (ctsm51d130_ne30pg3_GSWP3V1_LMWG_dev8_1850[AD, pAD])

[wwieder]

Description:

Parameter values for kc_nonmyc and kn_nonmyc switched in CLM5 & CTSM5.1 .

@ecaas noticed low mycorrhizal N uptake rates in CLM5.1 simulations and worked with @rosiealice and FUN developers to determine that parameter values for non-mycorrhizal N uptake costs (kc_nonmyc and kn_nonmyc ) in FUN were switched CTSM Issue #2120, see also discussion #2098.

@linniahawkins did some tests with the sparse grid to quickly evaluate the global impact of this bug and found lower steady state C pools and fluxes, but similar behavior in transient simulations. This simulation is intended to more fully evaluate impacts of fixing the parameter bug in global CLM land only simulations. Given differences in the code base, it may be necessary to create a new parameter file for the main development branch of the model.

Corrected values for these parameter from @ecaas are below

Same as #1 plus new paramfile:

Also from #1 I copied CaseDocs/datm.streams.xml to this case rather than modifying the /cdeps directory, which is what Keith's setup does.

I'd do these with the same compset @olyson is using for the arctic vegetation runs (I'm assuming 1 degree, bgc crop, spinup and historical).

[rosiealice]

Just wanting to note that for CLM5 we treated the magnitude of these numbers as tuning parameters, and that is why some of them are an order or magnitude different....

[slevis-lmwg]

@olyson and I talked, and I am setting up the spinup as he did in #1.
This way we can compare to his control.

[wwieder]

When this is done, let's look at PFT survival compared to the control simulation.

[slevis-lmwg]

@wwieder
Keith and I resolved the regrid issues with the diag. pkg.
Diagnostics are now posted above for this case, as well.

[wwieder]

I had wanted to start looking at PFT survival, but there doesn't seem to be the same information on these h1 files, presumably because of the ne30 grids were you able to preprocess these h1 datasets?

[slevis-lmwg]

I think that there is mapping info in the files, but maybe it looks different than before. For example I found these relevant variables in one of the daily files:
ncdump ctsm51d130_ne30pg3_GSWP3V1_LMWG_dev8_1850.clm2.h1.0020-12-31-00000.nc

I would be happy to go over the code together to figure out what needs to be done.

[wwieder]

Thanks Sam. I'm wondering if there's more information to when we generate single variable time series? For example this notebook works for PFT output generated by the CESM2-LE, but when I point it to your h1 files it doesn't work?
