The North China Plain (NCP), with an area of ~140,000 square kilometers, is among the most important agricultural producing bases in China. In addition to canal irrigation with surface water from the Yellow River, the NCP also needs much groundwater for intensive irrigation. Spatiotemporally continuous and daily evapotranspiration (ET) estimates of high spatial resolution could be valuable for improving our understanding of agricultural water consumption across the NCP, and also for improving water use efficiency for better agricultural water resource management practices over similar regions globally. This ET data set at 1 km spatial resolution and daily timescale across the NCP from Jan 2008 to Dec 2019 was generated using two source energy balance model (TSEB) and data fusion. The accuracy is generally comparable and even higher than published results, with our ET data set featuring spatiotemporal continuity and high spatial resolution for a decade. Furthermore, this data set and associated approaches are valuable for performing daily, monthly, seasonal, interannual, and trend analyses of ET in the NCP and similar regions globally.

In this experiment, four piezoelectric ceramic sensors were prepared, and a traditional commercial acoustic emission sensor was arranged near the piezoelectric ceramic sensor. The data collected by the two sensors were compared. There are four groups of data, and each group of data includes the data of a piezoelectric ceramic sensor and a commercial acoustic emission sensor in a similar position. The test shows that the embedded cement-based piezoelectric ceramic sensor has high sensitivity and can work under quasi-static load. It is of great significance for the monitoring of internal fracture of mass concrete structure.
