TEM Test-site


Note: The Danish TEM Test-site is no longer accessible for external users. 

The Danish TEM Test-site located outside Aarhus (Lyngby) was established in 2001. Over the years the test site has been refined and extended, and today the test site consists of a well described resistivity model (the reference model) and two ~1 km reference lines. The reference model is defined to a depth of ~280 m and holds detailed shallow resistivity information based on additional ERT measurements and EL-log drillings. The Test-site is used for calibration and validation of both ground based and airborne TEM-instruments.
