−	The z2sig.def file contains the pseudo-altitudes (in km) at which the user wants to set the vertical levels. Note that levels should be unevenly spread, with a higher resolution near the surface in order to capture the rapid variations of variables there. It is recommended to use the altitude levels as set in the ''z2sig.def'' file provided in the ''deftank'' directory.
