This dataset contains the biophysical measurements (mineral nitrogen, percent carbon, percent nitrogen, percent soil moisture, particle size analysis and aggregate stability) from soil collected from farmers' fields in the Halaba district, Southern Nations, Nationalities and Peoples' Region in Ethiopia, after the drought of 2015-2016. Eighteen farms from four kebeles (Asore, Lay Arisho, Konicha and 1st Choroko) were sampled. Soil cores were taken from fields classed as "home", "near" and "far" from the homestead and were taken from two depths (0-20cm and 20-50cm). Soil cores were taken after the El Niño event of 2015/16, so reflect the resilience of different areas of the farm to drought. This dataset was collected as part of the NERC-funded project Building Resilience in Ethiopia's Awassa region to Drought (BREAD).

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)
In August 2020, two natural slopes just outside Kuala Lumpur, Malaysia, were instrumented with sensors to measure soil suction and volumetric water content (VWC), and rainfall. At present, data has been collected at the two sites for approximately one year, although measurements are expected to continue for the foreseeable future. The measurements taken are aimed at providing guidance on the stability of soil slopes in response to changing climatic conditions. Data is currently being analysed by researchers at Durham University and the National University of Malaysia (UKM).
The datasets consist of soil moisture (hourly-weekly), river stage (1 min), and groundwater level (hourly) collected as part of the BRAVE project (NE/M008827/1 and NE/M008983/1) to understand the resilience of boreholes in low-yielding aquifers in the River Volta Basin to climate. The data were collected from physical observatories in Sanon (Burkina Faso) and Aniabisi (Ghana). Soil moisture data were logged hourly beneath contrasting land uses and roaming soil moisture surveys were also undertaken across a wider access tube array. River stage was monitored at the catchment outlet in Sanon and groundwater levels were measured in both catchments.
