How to interpret the outputs in column level

[jinmuluo]

Dear CTSM Community members,

It's a normal question. Can I output my simulation result in column value, and how can I interpret it like plotting different maps in natural soil or agricultural soil?

Thanks!

Yes, you can. See here:

1.2.3. Customizing CLM’s namelist — ctsm release-clm5.0 documentation

Interpretation of the model output is up to the user.

Hi Sam,

Thanks! If I output my simulation results in column, do you know how to filter the result with land type. For example, I want a global total runoff in agricultural soil etc.

Best,

There will be variables in the history file output that will help. For example,

cols1d_lon and cols1d_lat will identify the lat/lon of each column
cols1d_itype_lunit will identify the landunit type of each column

An ncdump -h on the file provides global attributes that identify the pft, column, landunit type ids, e.g.,

:ltype_vegetated_or_bare_soil = 1 ;
:ltype_crop = 2 ;
:ltype_UNUSED = 3 ;
:ltype_landice = 4 ;
:ltype_deep_lake = 5 ;
:ltype_wetland = 6 ;
:ltype_urban_tbd = 7 ;
:ltype_urban_hd = 8 ;
:ltype_urban_md = 9 ;
