How to generate 0.01° CLM surfdata?

Hi all,
I am building a 0.01° high-resolution surface dataset (surfdata) for the Qinling Mountains region (approximately 105.01–111.51°E, 32.08–34.94°N) based on CESM/CLM (CTSM) for regional simulation experiments.

My plan is:
First, generate a 0.01° Qinling surfdata file using default CLM datasets, then replace the coarse-resolution data in this surfdata file with my own high-resolution datasets.

So far I have completed the following steps:
  1. Generated a 0.01° regular lat-lon grid in SCRIP format (SCRIPgrid.nc).
  2. Converted the SCRIP grid to a CLM mesh file (lnd_mesh.nc) using ESMF_Scrip2Unstruct.
Questions:
  1. With the SCRIP grid and mesh file already prepared, what is the standard workflow to generate a CLM-compatible surfdata file next? Do I need to use the official default CLM datasets?
  2. If official default datasets are required, which specific datasets do I need, and where can I obtain them?
