Full coupler history files for all CMIP6 CESM2 SSP370 ensemble members?

What version of the code are you using?
CTSM5.2.001

Hi all, I was trying to run three land-only simulations under SSP3-7.0 scenarios. Each would be forced by a different CESM2 ensemble member so we can capture internal variability in the atmospheric forcing. The cases are: b.e21.BSSP370cmip6.f09_g17.CMIP6-SSP3-7.0.101/102/103

I could find some coupler history files from /glade/campaign/collections/cmip/CMIP6/cpl_hist/. However, I found that only the 102 case contains *ha2x3h*, *.ha2x1hi.*, *.ha2x1h.* files, while the 101 and 103 cases only have *.ha2x1d.* files. Based on my understanding, CPLHIST mode needs all these files to provide atmospheric forcing.

I am wondering if the ha2x1hi/ha2x1h/ha2x3h files for SSP3-7.0 members 101 and 103 archived anywhere else?

We are basically trying to look for future-climate atmospheric forcing data with at least three ensemble members. If there are other available cpl_hist datasets that are suitable, I would greatly appreciate any suggestions. For example, I also explored the CESM2-LE coupler history archive at: /glade/campaign/cesm/collections/CESM2-LE/cplhist/, but the cpl_hist files there are also not complete.

Thank you so much for the help!

I do not know of another cpl_hist directory for CESM2 data unfortunately. Historically, we do not keep coupler history files around long term. (That might change for CESM3 though.)
