Questions regarding ctsm52landusedatatool inputs and LUH2 data

[Jeline]

Hello everyone,

I need to create own CLM surface datasets, so I am currently using the ctsm52landusedatatool to generate the landuse rawdata.

I downloaded the tool from https://github.com/lawrencepj1/ctsm52landusedatatool, along with the example files and input data from https://zenodo.org/records/15509127. These inputs include the globalclm52histLUH2namelist file and EarthStat datasets such as clmcurrentsurfdb, clmLUHforestdb, clmLUHpasturedb, clmLUHotherdb, clmLUHc3anndb, clmLUHc4anndb, etc.

During the process, I have the following questions:

1. In the globalclm52histLUH2namelist file, the path for refstatesdb is listed as: /glade/p/cesm/sdwg_dev/thesis/data/cesm_tools/lumip52/LUH2_HIST_GEOG_DEG025/states.nc. I guess this is an internal path on the NCAR HPC system, which I do not have access to. What is the difference between this file and the states.nc file available from the official LUH2 website? Can I directly use the states.nc file downloaded from the LUH2 website?
2. In the globalclm52histLUH2namelist file, the datasets clmcurrentsurfdb, clmLUHforestdb, clmLUHpasturedb, and clmLUHotherdb each contain data for only a single year (2005), while clmLUHc3anndb, clmLUHc4anndb, clmLUHc3perdb, etc., contain 55 years of data (1961–2015). What is the reason for this difference?

I have attached the globalclm52histLUH2namelist file. Thank you very much for your help!

I think the answer to (1) is YES you can, as I suspect there is no difference between the files.
I do not know the answer to (2).
