Datasets description

<p>This data is for further processing using sentinel2 reflectance product data. The original data is the 10-meter monthly Sentinel 2 reflectance mosaic data set in Xinjiang. The leaf area index data is extracted through machine learning. The quality control mainly uses the 2020-2021 leaf area measurement data in Xinjiang for model construction and verification. </p>

Base information
data size 1.4 TiB
data format grid
Coordinate system WGS84
Projection CGCS2000

Data source description

The main source of Sentinel-2 reflectivity data is downloaded from ESA. The rest of the auxiliary data sources are on-site measurement data and are generated independently.

Data processing method

This dataset uses empirical models to calculate vegetation coverage. The data resolution is 10m, and the leaf area index used for this model calculation is obtained from field collection.

Data quality description

 Quality control mainly uses measured leaf area data from 2021 to 2023 in Xinjiang for model construction and verification. The error of this dataset in crops and grasslands does not exceed 20%.
