I have encountered a question: the output data in archive/Simu.case2/ice/hist/$CASE.cice.h.xxxx.nc is missing in the left-upper region, as shown in fig.Why?sic1-1.png.

This is very strange indeed. Can you tell me what version of the model this is? What grid combination?

My cesm is the version 1.2.2.1. I creat my case by the commend create_newcase -mach userdefined -res f19_f19 -compset FAMIPC5 -case Simu.case4. I conducted one monthly simulation from 2000-01-01 as a test, then I found the question. Except the above, I didn't conducted other modifies. So is it related to the version?

Should not be the version of the code. What is the SST/IFRAC dataset you are using here? What if you change your colorscale? I am guessing you have values above 1 here for sea ice concentration. There is a procedure called "diddling" where values of IFRAC can be outside the bounds of 0 to 1. This is so the time interpolation to daily gives you back the monthly mean values exactly. In the SST/IFRAC file, there should be a "prediddle" field that should look correct. The CICE model should bound the sea ice concentration appropriately. Have a look in the CICE history files using ncview or panoply.

Thanks! The used SST data is sst_HadOIBl_bc_1.9x2.5_1850_2012_c130411.nc. I will check it!
Besides, the reason from the version has been excluded. But I just remember I modified the code in ice_itd.F90 because of an error " forrtl: severe (408): fort: (2): Subscript #1 of the array ATRCR has value 1 which is greater than the upper bound of 0 ". When "Ice blocks " increased to some value with modifying "NTASKS_xxx", the error occurred. So I fixed the code in ice_itd.F90 follow the below method:
call compute_tracers (nx_block, ny_block, & icells, indxi, indxj, & ntrcr, trcr_depend, & atrcr , aice(:,:), & vice (:,:), vsno(:,:), & trcr(:,:,:)) =>
remove the explicit array syntax : call compute_tracers (nx_block, ny_block, & icells, indxi, indxj, & ntrcr, trcr_depend, & atrcr , aice, & vice , vsno, & trcr) . the reference post: Error running compset FSDWSF (ERT)
This resulted in the missing?

You are right! The history data and plot are correct using ncview or panoply. Thanks!
