CESM2 LENS BHISTsmbb Restart Files

I am trying to do branch/hybrid runs using 10 ensemble members of CESM2-LENS BHISTsmbb: 1011.001, 1031.002, 1051.003, 1071.004, 1091.005, 1111.006, 1131.007, 1151.008, 1171.009, and 1191.010, with restart files beginning around 2000-01-01-00000.

I found some restart files for BHISTsmbb in the directory /glade/campaign/cgd/cesm/CESM2-LE/restarts/. However, for these 10 members, I cannot find restart files available around the year 2000, and the earliest I can find are from 2010.

Could anyone upload or share the restart files around the year 2000 for these members? Thank you.

I'll see if these restarts can be transferred here.

These are the only CESM2-LE runs with year 2000 restarts:

Thank you strandwg. It seems that among the 100 ensemble members of the CESM2-LENS historical runs, only the 10 members I specifically need (listed below) do not have restart files available around the year 2000 (or between 1900–2000). Do you know why these 10 members did not retain restart files like the other members? I noticed that these 10 members have available 6-hourly data on the data website for CESM2-LENS, whereas the other members do not. Is there any connection between the availability of 6-hourly data and the lack of restart files for these 10 members?

I originally planned to perform some topography sensitivity experiments on the simulations of these 10 members from the year 2000 (or earlier), so I need their restart files. Since you suggested that these restart files might not be available, I think I may have to give up the sensitivity experiments for these members. I would appreciate it if anyone could provide more information on this issue. Thanks!

Those ten runs saved high frequency output, which is what distinguishes them from the rest. They do have restarts, not just 2000 specifically.

Must you use these specific runs and must you have year 2000 restarts, or can you be a bit more flexible?

Thank you. I would like to know if these 10 members have restart files available between 1980 and 2010.
