The dataset is the 30 meter resolution leaf area index (LAI) product from 2010 to 2019 over the Tibetan Plateau. The LAI product was retrieved using Landsat time series data and physically based radiative transfer model, and it is the annual maximum synthetic leaf area index product. When validated with the simulation data set, the root-mean-square error (RMSE) was 1.16. Leaf area index highly integrates the horizontal coverage and vertical structure of vegetation, and is an important structural parameter of the vegetation canopy, which can provide data product support for the research and applications in land surface process simulation, resources survey, ecological environment monitoring, global change research and other fields.

File naming and required software

1)File name rules: leaf area index (LAI) products are stored in folders in 5×5 degree blocks, using WGS84 coordinate system. The file naming rule is: LAI_year_longitude_latitude, such as LAI_2010_70_35.tif represents the maximum composite LAI in 2010 of the 5×5 degree block with 70 degree longitude and 35 degree latitude in the lower left corner; 2)How to use the dataset: the leaf area index products can be opened by ArcGIS, Envi, QGIS and so on. The valid value ranges from 0 to 8. The background filled value is NAN, and the "LZW" lossless compression is performed.
