| 14 | ! Read input profile of tracers listed in traceur.def |

| 17 | !---------- |
|---|
| 18 | ! - If no input profile found, q(traceur) and qsurf(traceur) set to 0, except: |
|---|
| 19 | ! - q(co2) = 0.95 |
|---|
| 20 | ! - q(hdo) = q(h2o)*2*155.76e-6*5 |
|---|
| 21 | ! |
|---|
| 22 | ! - igcm is not available at this part of the code |
|---|
| 23 | ! |
|---|
| 24 | ! - To ensure that major isotopologue input profile is read before compute minor isotopologue profile, the |
|---|
| 25 | ! calculation is performed at the end of the subroutine |
