Fig. 2

The identification index to represent the quality of the ITL depth determination. (a) ITL not existence or ITL in existence, but not identified (h = 0). (b) Identified ITL depth shorter than the real ITL depth. (c) Perfectly identified ITL depth. (d) Identified ITL depth longer than the real ITL depth. (e) Identified ITL depth at z(0.7), i.e., thermocline not existence. Here, the ITL depth is marked by a circle. The thick line in each figure is a single linear function fitted to the temperature profile data.
