PATM: specification and references

I am setting up to specify atmospheric pressure distribution for my regional croco configuration. I am using BULK_FLUX, and have now also specified “define READ_PATM” and “define OBC_PATM” in my cppdefs.
For reference, can anyone point out published studies using this options?
Also, I’m getting runtime error: “GET_BULK - ERROR: unable to find forcing variable”. Perhaps I specified the wrong variable name in the bulk forcing file - is “patm2d” not the variable name that croco expects? Is there anything else I should include? Based on the code it seems that the parameter “paref” is hard coded and should not be specified externally.

Turns out that the variable name should be “pmer”.
Still interested in references, in case anyone is familiar with some.
