Hi all,
I am running CESM1.1.1 using compset E_1850_CAM5 for a custom paleoclimate run (45 ka) on Harvard's computer (odyssey, or sometimes called cannon). I have created my own lnd and ocn domain files using gen_domain (as described in this guide) and subsequently set my LND/ATM/OCN/ICE_DOMAIN_FILE variables to those newly-created domains. I have also set my DOCN_SOM_FILENAME to a forcing dataset I found here (specifically, I am using pop_frc.b.e11.B1850C5CN.f09_g16.005.150217.nc). My model is crashing due to a domain checking issue (error from my cpl.log output below):
(seq_mct_drv) : Performing domain checking
(seq_domain_check) --- checking ocn/ice domains ---
(seq_domain_check_grid) the domain size is = 854
(seq_domain_check_grid) maximum difference for mask 0.00000000000000

(seq_domain_check_grid) maximum allowable difference for lat 0.100000000000000E-01
(seq_domain_check_grid) ERROR: incompatible domain grid coordinates
I thought that since I set the ocn/ice domains to the same file, this would not be an issue. I do notice though that when I compare the SOM dataset (pop_frc.b.e...etc) latitude to my ocn domain latitude, the maximum difference is 27.7 (see max difference for lat above), so I think the issue is coming from there. When I plot the latitudes using panoply, mine is indicative of a displaced pole while the pop forcing files in general from the repository linked above appear much different. The longitudes between the two files also vary.
For a custom paleo run, do I need to create my own SOM forcing file? If so, how? Or, is there somewhere to get a displaced-pole SOM forcing file for E_1850_CAM5 (I am aware that the forcing file I use is for CAM5_CN)?
Let me know, thank you!
