Setup ndep, aerosols, and CO2 for CRUJRA -- the gap year between 2014-2023

[wwieder]

Brief summary of bug

Running historical cases with ctsm5.3.041 I've noticed a few things should be improved to make sure cases are set up out of the box.

General bug information

• HIST compsets have co2 streams that end in 2014 but CRUJRA goes through 2023 manually using the following in user_nl_datm_streams

co2tseries.20tr:year_last = 2023
co2tseries.20tr:datafiles = /glade/campaign/cesm/cesmdata/inputdata/atm/datm7/CO2/fco2_datm_globalSSP3-7.0_simyr_1750-2501_CMIP6_c201101.nc

• manually setting ndep_taxmode = 'extend' in user_nl_clm, but this should also be setting to correct file and year_last

presndep.hist:datafiles = /glade/campaign/cesm/cesmdata/inputdata/lnd/clm2/ndepdata/fndep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.002_1849-2101_monthly_0.9x1.25_c211216.nc
presndep.hist:year_last = 2023

• Do we need to also think about the handling of Aerosols
• Population density is handled with new CMIP7 data, already on the 5.4 tag?
• What else?
• reseeding on a branch #3257 is another default that could be addressed here, though is it MORE URGENT than the rest in this list?
• PE layout could be improved? ne30 case requests 13 nodes and 16 tasks and only getting 55 y/day in historical cases. This PE layout is the same as a f19 HIST case
• For more see card in Upcoming Tags

These are things that cover I cases and not coupled cases. The first needs to be addressed in CDEPS and then the updated CDEPS tag brought into CTSM. The second two can be addressed inside of CTSM.
