From May to November in 2020, 3 nodes were set up at Yucheng station in Shandong Province of China for observing the leaf area index (LAI) measured by SBLX-034 Sensor Network System. First, the authors chose the data observed between 10 am and 15 pm, and filter out the time when there were valid data. Then, according to the temporal and spatial correlation between the nodes, the time-series neural network NARX was used to build the model, and the abnormal time data with the model prediction error greater than 1 was eliminated. The LSTM neural network was used to test the rule of the processed data. Finally, the daily data was averaged to obtain the leaf area index daily dataset from observation nodes in Yucheng of Shandong Province, China (2020). The dataset is consisted of: (1) geo-location of 3 wireless sensor network nodes at the Yucheng Station; (2) leaf area index daily data at three nodes from May to November in 2020. The dataset is archived in .xlsx, .shp and .kmz data format with data size of 49.1 KB (compressed to one single file with 42.5 KB).
