BIFoR site of Mill Haft, Staffordshire, UK. Temperature from Fiber Optics Distributed Temperature Sensor (DTS). Soil moisture from Active DTS technique and from FDR point probes (NERC grant NE/P003486/1)
The data comprise of temperatures (degC) from a fibre optic distributed temperature sensor and soil moisture in the form of volumetric water content (VWC), expressed in m3/m3. The measurements were performed in a vegetated hillslope in Staffordshire, UK, in the context of the NERC funded project DiHPS: A Distributed Heat Pulse Sensor Network for subsurface heat and water fluxes. The site was equipped with: 15xVWC point probes (5TM, Decagon Devices) installed at 5 locations along the hillslope. At each location, 3x5TM probes were inserted in the soil at depths of 0.10m, 0.25m, 0.40m from the soil surface 1,512m of fibre optic cable for Active DTS measurements. The fibre was buried in the soil in three overlapped loops of 504m each at 0.10m, 0.25m, 0.40m. The measurements from the 5TM were used to infer a site specific empirical relation to obtain soil moisture from Active-DTS measurements, following the approach from Sayde et al., WRR, 2010 (https://www.researchgate.net/publication/241060722_Feasibility_of_soil_moisture_monitoring_with_heated_fiber_optics)

Data Quality
Soil temperature (DTS): DTS continuously measuring every 30s and 0.25m spatial sampling over the entire 1,512m of buried fibre optic cable. VWC (A-DTS): A-DTS tests were performed by heating in sequence the cable at 0.40m for 930s, then the cable at 0.25m and finally at 0.10m. Applied power rate was 5W/m. Each A-DTS test was automatically repeated 4 times per day (starting at 02:00, 08:00, 14:00, 20:00). DTS temperatures during each of the heating cycles were time-integrated to produce cumulative temperature values at each 0.25m spatial sample along the fibre optic Cumulative temperatures were converted into VWC by means of a site specific empirical relationship carried out during the first A-DTS tests performed in 2015-2016. A detailed description of the installation, DTS data, and calibration of the system is contained in Ciocca et. al, 2018 (in preparation)
