Abstract：
LAI observation calibration and validation network at Hebei Luancheng Station (Central coordinates: 114°41'34.80"E，37°53'22.51"N) was completed on March 22, 2019. It is one site of the China LAI observation calibration and validation network (“China LAI Cal-Val ”for short), which was initialed in 2018. The instruments was LAI Wireless Sensor Networks Observation System (“LAI-NOS” for short). The LAI-NOS instruments can continuously and automatically obtain continuous LAI data, without manual intervention. Luancheng Station was a typical northern station of “China LAI Cal-Val” network station, its function was the LAI Cal-Val for the wheat- maize rotation farmland system in the warm temperate zone of China, wheat in winter and maize in summer. The selected dataset contains LAI data collected in wheat growing season at Luancheng Station from March 25 to June 10, 2019 (wheat greening to maturity period), from three adjacent selected “LAI-NOS ” nodes data (0901, 0902 and 0904) , based on the steady window algorithm by extracting data of early morning and evening. The dataset includes: (1) the geographic location of three nodes at Luancheng Station in 2019; (2) daily LAI data of the three “LAI-NOS” nodes at Luancheng Station from March 25, 2019 to June 10, 2019. The dataset is archived in .xlsx, .shp and .kmz data formats, and consists of 9 files with data size of 25.6 KB (compressed into 2 files, 21.9 KB).Browse
