This file contains a single namelist called JULES_TRIFFID that sets parameters relevant to the TRIFFID submodel.

6.16.1. JULES_TRIFFID namelist members

This namelist is used to read PFT parameters that are only needed by the dynamic vegetation model (TRIFFID). Values are not used if TRIFFID is not selected.

Note

Where a quantity is said to have units of “/360days”, this means that it is an amount per 360 days.

Note

If the crop model is on (i.e. ncpft > 0), only nnpft = npft - ncpft values will be used for each variable.
