Request for the exact aerosol-deposition input used by CESM2 CMIP6 land-hist r1i1p1f1

[Hano]

Hello,

I am reproducing the CESM2 CMIP6 land-hist experiment

i.e21.IHIST.f09_g17.CMIP6-land-hist.001
(CESM2_land-hist_r1i1p1f1)

on an external HPC system.

The official CaseDocs reference the following aerosol-deposition file:

/gpfs/fs1/p/cgd/tss/people/oleson/CLM5_aerodep/
aerodep_clm_hist_b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensmean_1849-2015_monthly_0.9x1.25_c180926.nc

However, this exact file is not present in the public CESM inputdata
SVN/FTP repository. The public repository contains only:

aerosoldep_WACCM.ensmean_monthly_hist_1849-2015_0.9x1.25_CMIP6_c180926.nc

Could you please:

1. Confirm whether these two files are scientifically or bitwise identical
apart from their filenames;
2. If they are not identical, provide the exact land-hist file through the
CESM inputdata repository, anonymous FTP, or a Globus guest collection;
3. Provide its byte size and SHA256 or MD5 checksum;
4. Confirm its provenance and whether it is the exact input used for
i.e21.IHIST.f09_g17.CMIP6-land-hist.001.

The intended reproduction period is 2001–2014 using GSWP3 meteorological
forcing.

Thank you.

I suspect that they are identical from the similarity in their filenames and from the fact that the aerosoldep file was also created by @oleson on the same date.

I do not see the aerodep file, either; however, I see aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_1849-2101_monthly_0.9x1.25_c201101.nc, which looks like the SSP370 version tacked on to the historical, as documented in the history attribute:

ncrcat -O /glade/p/cesmdata/cseg/inputdata/atm/cam/chem/trop_mozart_aero/aero/aerosoldep_WACCM.ensmean_monthly_hist_1849-2015_0.9x1.25_CMIP6_c180926.nc aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_2015-2101_monthly_0.9x1.25_c190402.nc /glade/p/cesmdata/cseg/inputdata/atm/cam/chem/trop_mozart_aero/aero/aerodep_clm_SSP370_b.e21.BWSSP370cmip6.f09_g17.CMIP6-SSP3-7.0-WACCM.001_1849-2101_monthly_0.9x1.25_c201101.nc

@oleson do you remember?

They are bitwise identical:

cprnc /glade/campaign/cgd/tss/people/oleson/CLM5_aerodep/aerodep_clm_hist_b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensmean_1849-2015_monthly_0.9x1.25_c180926.nc /glade/campaign/cesm/cesmdata/inputdata/atm/cam/chem/trop_mozart_aero/aero/aerosoldep_WACCM.ensmean_monthly_hist_1849-2015_0.9x1.25_CMIP6_c180926.nc
