Abstract

The observation and measurement of ecohydrological processes have been witnessed a huge progress in terms of novel ideas, methodologies, and techniques. Many cutting-edge observing techniques, e.g., stable isotope, wireless sensor network, cosmic ray probe, multi-source remote sensing, are continuously introduced and widely applied. As the first chapter of this book, this chapter introduces the progresses, challenges, and perspectives of observing ecohydrological processes. We first introduced the key states and fluxes that control the ecohydrological processes and novel techniques that allow those controlling factors to be quantified. However, we found that knowledge gap remains, including: (1) improving the observation ability to understand and quantify the ecohydrological processes, (2) integrating multisource observations into a dynamics model to accurately estimate the state and flux variables of ecohydrological processes, (3) developing upscaling approaches through system observations to understand the scaling issue, and (4) estimating representativeness error to quantify the uncertainties. To this end, we pointed out the potential directions for filling these gaps, including: (1) to better translate remotely sensed data into information that helps us better understand ecohydrological processes and better inform land-surface models, (2) to better quantify the roles of subsurface processes in ecohydrological processes, (3) to develop observational systems that allow ecohydrological processes to be captured across different scales and across compartments, (4) to use well-instrumented watersheds as test beds of new concept for ecohydrological observations, (5) to combine monitoring and controllable and synthetic observation experiments, (6) to utilize technical advancements in new models, and (7) to integrate observation systems with integrated models, data services, and decision making. Overall, this chapter provides an insight into the-state-of-art of observing ecohydrological processes.
