I have been running CTSM 5.1.dev171 in CPLHIST mode with 1-hourly/3-hourly atmospheric forcing saved from previous fully coupled CESM simulations (following SSP245, 2016-2070). I want to use this forcing to run CTSM offline as i have been doing, but now with FATES active. The only thing I care about is using this atmpsheric forcing, nothing else needs to match my previous runs, and I do not care about transient land use or CO2. I do not have the computer time to do my own spinup. My question is, has anyone done a FATES spinup (f09_g17) I2000 (or where can I check if this exists)? If so, would it be safe for me to use the finidat from this spinup run to initialize my future FATES simualtion with my own forcing? Thanks
