vegetation type in CLM

Hi there,

I am trying to use the output data of CLM models.
I was looking for the parameter which define the vegetation types.
I have found "pfts1d_itype_veg" parameter, but I am not sure if it is an appropriate one.
I was wondering if anyone can advice me any other useful parameters regarding vegetation types?
In addition I have found that "pfts1d_itype_veg" is in one dimension so I could not find any spatial and temporal variabilities.

There should be a variable called "PCT_NAT_PFT" on the primary (h0) CLM history file:

float PCT_NAT_PFT(time, natpft, lat, lon) ;
PCT_NAT_PFT:long_name = "% of each PFT on the natural vegetation (i.e., soil) landunit" ;
PCT_NAT_PFT:units = "%" ;
PCT_NAT_PFT:cell_methods = "time: mean" ;
PCT_NAT_PFT:_FillValue = 1.e+36f ;
PCT_NAT_PFT:missing_value = 1.e+36f ;
PCT_NAT_PFT:landunit_mask = "unknown" ;

and if the BGC model is active, there is a variable called "PCT_CFT" for the crop types:

float PCT_CFT(time, cft, lat, lon) ;
PCT_CFT:long_name = "% of each crop on the crop landunit" ;
PCT_CFT:units = "%" ;
PCT_CFT:cell_methods = "time: mean" ;
PCT_CFT:_FillValue = 1.e+36f ;
PCT_CFT:missing_value = 1.e+36f ;
PCT_CFT:landunit_mask = "unknown" ;

I don't normally follow the Data Models Forum, so please post future CLM-related questions to the CLM Forum, thanks.
