A global estimate of monthly vegetation and soil fractions from spatio-temporally adaptive spectral mixture analysis during 2001-2022

This dataset is a global estimate of monthly vegetation and soil fractions using spatio-temporally adaptive spectral mixture analysis from 2001-2011. The file is a compressed month-by-month GeoTIFF data for each year, according to the grid of longitude 60° and Latitude 50°. Since the dataset for each year includes 216 files, named as “SMA_year_(month-1)_gridid.tif”, like “SMA_2001_0_0.tif”. The dataset from 2012-2022 can be found in another Zenodo (10.5281/zenodo.8331843) The dataset can be also exported from GEE by our code or achieved by request from authors.
