***General Introduction***
This LAI data sets were generated by reprocessing the MODIS version 6.1 LAI products. 
The raw data used include the MODIS LAI Version 6.1 products MCD15A2H (2002.7.4-2021, https://lpdaac.usgs.gov/products/mcd15a2hv061/), MOD15A2H (2000.2.18-2002.6.26, https://lpdaac.usgs.gov/products/mod15a2hv061/) and MODIS Land Cover Type product MCD12Q1 (2001-2021, https://lpdaac.usgs.gov/products/mcd12q1v061/).

The algorithm is mainly based on the two-step integrated method developed by Yuan et al. (2011, https://doi.org/10.1016/j.rse.2011.01.001), and the method of background value calculation was updated. See http://globalchange.bnu.edu.cn/research/laiv061 for more details.

***Description of the data in this data set***
These monthly LAI data were provided at 0.5-degree resolution covering the period 2000-2021. Data of each year is stored in one NetCDF file, namely lai_monthly_0.5_{YYYY}.nc.
YYYY: year (2000-2021)

Projection: Geographic Coordinates
Value Range: 0~10 
Filled Value: none
Units: m2/m2
