What ISM phase does CI emission trace?

Neutral, atomic carbon exists in the interstellar medium between regions where singly-ionized carbon and carbon monoxide lock away the carbon. While it's known this should be in regions where hydrogen is predominantly molecular, it is not known whether the [CI] emission traces mostly a diffuse or dense portion of the molecular gas.
