Looking for suitable initial conditions files with 56 layers

[lqingq]

I am currently using the CESM version (CAM_MAM4_MOSAIC) to carry out some simulation work. The grid is 0.9×1.25°, set to 56 levels, running from 2005 to 2020, and the compset used is FCnudged. The initial field files (ncdata) I have found so far are all 32-levels, and now I am looking for suitable initial conditions files with 56 levels.
