“…However, it is worth considering whether attempts to realize generic and realistic uncertainty quantification of Earth observation data too often fail at very early stages. For example, commercial manufacturers of Earth observation systems might not reveal internal functionality, calibration details, etc., of their proprietary sensors and might lack a systematic sensor decomposition concept (Bumberger et al, 2015) for controlled assessment of all aspects of the measurement uncertainty of a sensor (Demuth et al, 2015).…”

“…A DP system was developed that consists of a sampling or logging tool attached to a drive head, that is pushed into the surface by powerful hydraulic equipment. To perform subsurface vertical parametrization, the tool is equipped with different types of sensors that can measure electrical resistivity, hydraulic conductivity and characterize the subsurface distribution of volatile organic compounds [15][16][17][18].…”

In this study, we attempted to develop an in situ thermal conductivity measurement system that can be used for subsurface thermal exploration. A new thermal probe was developed for mapping both the spatial and temporal variability of thermal conductivity, via direct push methods in the unconsolidated shallow subsurface. A robust, hollow cylindrical probe was constructed and its performance was tested by carrying out thermal conductivity measurements on materials with known properties. The thermal conductivity of the investigated materials can be worked out by measuring the active power consumption (in alternating current system) and temperature of the probe over fixed time intervals. A calibration method was used to eliminate any undesired thermal effects regarding the size of the probe, based on mobile thermal analyzer thermal conductivity values. Using the hollow cylindrical probe, the thermal conductivity results obtained had an error of less than 2.5% for solid samples (such as Teflon, Agar Jelly and Nylatron).
