The term "cloud radiative center height/temperature/air pressure" is used in addition to "effective cloud height/temperature/air pressure" The verbiage "effective" is used in our group and in other groups as well (see: http://scrippsscholars.ucsd.edu/aevan/content/global-changes-effective-clou d-height), but then my NCDC contacts asked what "effective" means. So we thought the "cloud radiative center" terminology was more descriptive, but not as widely used as "effective".
Yes Jim, I mean height above ground level The bottom line is that I need some name to describe the fact that our retrievals correspond to a height within the cloud, not at cloud top. Our type of retrieval is not unique. Just about every satellite-based cloud property retrieval algorithm derives its information at this "effective" level. So, naming suggestions are welcomed.

(1) Is "cloud radiative center" a concept which is used outside your group? In general we define standard names for quantities which are generally used in the community. (2) Do you really mean "height" i.e. distance above the ground? Or perhaps you mean altitude or geopotential height or something else? (3) I guess you mean air_pressure - is that right?
