Hyperspectral imaging offers numerous advantages for studying ecosystem functioning and dynamics : It is non-intrusive, It allows high-frequency temporal characterization of a wide range of geoscience objects (e.g., sediment load, soils) and biodiversity science objects (e.g., functional traits of vegetation cover, species assemblages), It is central to several Earth observation space programs. Despite these advantages, on-site deployment of this technology remains limited due to the high (…)

Soil water content plays a crucial role in energy and water exchanges between the atmosphere and the land surface. This variable is highly dynamic in both space and time—even within a single watershed (ranging from less than 1 km² to over 100 km²) and throughout the year. Capturing this variability and its importance requires a network of in-situ sensors continuously measuring soil conditions, preferably at multiple depths within the top 50 cm of soil. These requirements call for simple, (…)
