Description: 
(1) Ground temperature time series in daily, monthly and annual resolution measured in permafrost boreholes, 
(2) Near ground surface temperature time series in daily, monthly and annual resolution measured at the PERMOS sites,
(3) Electrical resistivity tomography (ERT) time series in annual resolution measured at fixed profiles at the PERMOS sites,
(4) Terrestrial geodetic survey (TGS)time series in annual resolution measured on actively moving rock glaciers,
(5) related meta data. 
All data are obtained by the PERMOS Partner Institutions in the scope of the Swiss Permafrost Monitoring Network PERMOS and curated by the PERMOS Office.
