Abstract:

Leaf Area Index (LAI) is defined as the ratio of half total leaf surface area to the area of level ground, and is one of the key biophysical factors to characterize vegetation. Sentinal-2 LAI Validation Dataset of Winter Wheat in Yucheng, Shandong of China was developed based on the 107 points (field survey, May 9-16, 2020) to points (Sentinal-2 20200429, 20200519, LAI) validation between the LAISentinal (10m) and LAIfield in Yucheng, Shandong Province of China. The correlation analysis with five models showed that Coefficient of Determination (R²) ranged from 0.7249 to 0.767, suggesting 76.7% of the LAI variation in the field can be determined by LAISentinal in this region. The dataset includes: (1) LAI point data, including data in situ, LAI based on Sentinal-2, their difference, and the proportion of difference to the data in situ; (2) LAI based on Sentinal-2 data with 10 m resolution. The dataset is archived in .shp, .kmz, .tif and .xlsx data formats, and consists of 17 data files with data size of 215 MB (compressed into three files with 156 MB).
