The presence of massive ice-lenses in periglacial areas can be a direct proof of permafrost occurrence. Such evidence from trenches or construction sites in high-mountain areas can provide useful information. Massive ice can also be observed in rockfall scars and can represents evidence of permafrost.

Ground Surface Temperature (GST) is defined as the near-surface temperature of the ground (bedrock or surficial deposits), measured in the uppermost centimeters of the ground. GST is not a direct proof of permafrost existence but a proxy for estimating potential permafrost presence or absence in the subsurface and can be used for calibrating and validating numerical models. GST has to be distinguished from the Bottom Temperature of Snow cover (BTS), which is the temperature measured at the snow/ground interface in late winter. The APD does not collect raw GST data but the Mean Annual Ground Surface Temperature (MAGST) of a certain depth.

Temperature measured in boreholes (BH) is the most reliable evidence of permafrost presence or absence. BH data provides min/max/mean subsurface temperature at differing depth, maximum active layer thickness (ALT) and (if available) the depth of zero annual amplitude (ZAA). The APD does not collects raw borehole data but yearly synthesis data.
