Table 2: _Cont._The difference in handling the sites in this work and that in [PERSON] et al. [57] is that Serres has been classified here in the climatic zone D. The reason is that this site is exactly on the border of two zones (C and D, see map in Figure 3); [PERSON] el. [57] considered it in zone C.
