Convective cloud top height

This can be derived from modelled vertical profiles of temperature throughout the troposphere.  At any given grid point the convection scheme inspects the temperature structure of the model atmosphere progressively from the surface to 300hPa.  If there exists a level of free convection (LFC) the scheme searches upward to the level where the model parcel temperature becomes the same as the model environment temperature.  This is considered as the altitude where free convection ceases and is taken as the convective cloud top height.
