Agreed Without knowing more about their algorithm, it sounds like what LARC retrieves and wishes to archive, is (approximately) the geometric height above the surface that is one optical depth (at 11 um) from the cloud top (as defined by visible/lidar techniques). This could be called the "effective height" since a preponderance of the captured photons will have the blackbody temperature signature of the atmosphere at this height. So, I would splice-in "effective" height_at_effective_cloud_top_defined_by_infrared_radiation although I could live with height_at_cloud_top_defined_by_infrared_radiation I think practioners in the field would better understand the meaning of the former than the latter. c -- Charlie Zender, Earth System Sci. & Computer Sci.
