New population dataset for streams files?

[adrifoster]

TRENDY gave us a new population dataset (which is used in our fire models).

It's located /glade/derecho/scratch/afoster/TRENDY_2024/inputs/pop/population.nc right now. Compare to the default dataset we currently use which is /glade/campaign/cesm/cesmdata/inputdata/lnd/clm2/firedata/clmforc.Li_2017_HYDEv3.2_CMIP6_hdm_0.5x0.5_AVHRR_simyr1850-2016_c180202.nc

The old dataset only goes to 2016, whereas this new one goes out to 2023. Both are derived from HYDE. (HYDE 3.4 for the new one; HYDE 3.2 for our old one).

Should we update this at some point? @lifang0209 did you make this dataset?

In the CTSM SE meeting this morning we decided we would NOT bring this in for ctsm5.3.0 and likely not for this years TRENDY.

But, bringing this in as a ctsm6.0.0 type update would be a good thing to do. It won't change answers enough for it to be a problem to bring in alongside other tuning changes. There's not time to get it done for ctsm5.3.0.

@adrifoster It's important to extend the forcing data period to 2023 to correctly simulate the changes in human ignitions and suppression effects during 2016-2023. I have HYDE3.3. I could made new population density data for CLM6/CTSM6 based on HYDE3.4, but I cannot find it at the path you provided (/glade/derecho/scratch/afoster/TRENDY_2024/inputs/pop/population.nc).

Sorry @lifang0209 I moved it to /glade/campaign/cgd/tss/projects/TRENDY2024/inputs/pop/population.nc for long-term since it was in my scratch.

If you are able to update our population streams data that would be great!
