PFTs and surface data

[lamptey@ucar_edu]

Hello,
I have used a different data set to generate raw data. When I check each of my
pfts, they range from 0 to 100. I do this check in NCL before I write them to the
mksrf_pft.nc file.

I have to run the model (CLM) for the surface data to be generated. The model
requires that the 4 most abundant pfts in each grid cell add up to 100. The model selects the 4 most abundant pfts during the run.

How can I ensure that the 4 most abundant pfts add up to 100 for each grid
cell since I can not do this in my NCL script?

Thanks
Ben

Hi Ben,

If you created the mksrf_pft.nc file correctly, then the model will do the rest for you when it transfers the data from all the mksrf files into the single surface dataset file to be used in your runs. For an example of a correct mksrf_pft.nc, you could look at the default file that comes with the clm3. Use that as a template in creating your own.
