TL;DR: In this paper, a program called the Heihe Watershed Allied Telemetry Experimental Research (HiWATER) was implemented to improve the observability of hydrological and ecological processes, to build a world-class watershed observing system, and to enhance the applicability of remote sensing in integrated ecohydrological studies and water resource management at basin scale.

TL;DR: In this article, a multiscale observation experiment on evapotranspiration over heterogeneous land surfaces was conducted in the midstream region of the Heihe River Basin (HRB), which included a flux observation matrix, wireless sensor network, airborne remote sensing, and synchronized ground measurements.

TL;DR: The ecohydrological wireless sensor network (EHWSN), which has been installed in the middle reach of the Heihe River Basin, provides superior integrated, standardized, and automated observation capabilities for hydrological and ecological processes research at the basin scale.

TL;DR: Changes in the near-surface soil freeze–thaw cycle on the Qinghai-Tibetan Plateau can be used both as an effective indicator of the permafrost change and for mapping ofpermafrost stability.

TL;DR: In this paper, the authors introduce the Internet of Things (IoT) techniques to establish a prototype ecosystem monitoring system by developing innovative smart devices and using IoT technologies for ecosystem monitoring in isolated environments, including large-scale and nonintrusive instruments to measure evapotranspiration and soil moisture, in situ observing systems for CO2 and δ13C associated with soil respiration, portable and distributed devices for monitoring vegetation variables, and pressure trigger sensors for terrestrial vertebrate monitoring.
