AB  - This data is the lainet data set of small full corn field from June 25, 2012 to August 24, 2012. The lainet dataset includes the calculated original Lai data, the Lai data after 5-day average, and the longitude and latitude of the measurement node. All data is saved in Excel. Measuring instrument: Beijing Normal University self-made wireless sensor network leaf area index observer. The 5-day average processed data takes the sink node number as the form name, and each sheet stores the measurement data of all child nodes under a sink node. The original data records the Lai value that can be calculated by each node in all observation dates In each form of the above two types of data, the meaning of each column is as follows: measurement date, do, node 1, node 2,..., node n. Measurement method: lainet observation system consists of three types of sensor nodes, namely (1) sub canopy nodes, where the sensors are placed nearly horizontally upward to measure the transmitted radiation of the canopy, (2) upper canopy nodes, where the sensors are placed approximately horizontally upward to measure the total incident radiation of the sun, (3) sink nodes, It is used to receive and forward the data measured by (1) and (2) nodes
