C !DESCRIPTION: |
| 14 |
C In the case of GCHEM_SEPARATE_FORCING undefined, GCHEM_ADD_TENDENCY |
| 15 |
C will update passive tracer tendencies gPtr with gchemTendency, |
| 16 |
C the latter having been computed in GCHEM_CALC_TENDENDY, so that |
| 17 |
C they will be incorporated into regular timestepping in |
| 18 |
C PTRACERS_INTERGRATE. |
| 19 |
C IF GCHEM_SEPARATE_FORCING is defined, this routine is empty. |

C apply the tendencies computed in GCHEM_CALC_TENDENCY to the passive |
| 54 |
C tracers tendendy terms. The part of the code could also go into |
| 55 |
C ptracers_forcing and replace the call to gchem_add_tendency there, |
| 56 |
C but this way, no gchem-related header files and CPP-flags are required |
| 57 |
C within ptracers_forcing. |
