APD - Ground Surface Temperatures (GST)

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.

Supplemental Information: You can customize the template to suit your needs. You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-)

OnLine resource: Alpine Permafrost Data website
The Alpine Permafrost Data (APD) is an on-line service for collecting and sharing permafrost data in the European Alps. The main goal of the database is to provide periodic, consistent and homogenized datasets on permafrost state and evolution. This website is addressed to all researchers, technicians and permafrost lovers working in the Alps. Registration, data submission and updating of permafrost evidence is encouraged as well as the active participation in open discussions and database development.
