Follow Up on Tmd at 4degrees

Question

Thanks for clarification.

For a problem with no external forcing and homogenous profile, the density produced at 4 degree was 16. The variability with depth (500m) is linear and clear as shown, but the value is not tuned.

This looks like you are running salinity.  Is isalinity set to 1?

Comments

hello again,

No it is not (
  0                                                       ibubbler
  1                                                   itemperature
  0                                                      isalinity
  1                                                       idensity)

Also, even if you try to add SALINITY as output it is not applicable, because there is no salinity values. The only input is a temperature profile.

What is your DEFAULT_SALINITY value

---

The default value is 20, but is it used with isalinity set to 0?

---

Yes, this is the value that will be used in the density calculations.

Thank you!!!
