Solution to UKCA & UMUI Tutorial 5 Task 5.2

Back to the adding new chemical emissions tutorial

Task

You should now make the UKCA code changes to add your emission into the ALICE tracer. No run-time processing of this surface emission is required.

Solution

As no run-time processing of this field is required, the only changes that need to be made are those in ukca_setd1defs.F90

Code changes to ukca_setd1defs.F90

In ukca_setd1defs.F90 you should scroll-down to the code block controlled by the

          ELSE IF (L_ukca_strattrop .AND. .NOT. L_ukca_achem) THEN

statement and

increase the value of n_chem_emissions to 10.
Edit em_chem_spec so that it now includes ALICE:

                 (/'NO        ','CH4       ','CO        ','HCHO      ', &
                   'C2H6      ','C3H8      ','Me2CO     ','MeCHO     ', &
                   'C5H8      ','ALICE     ','NO_aircrft'/)
