Soil ECe 1984-2021 of croplands in drylands.zip

This dataset is a time series of soil salinity of cropland in drylands from 1984 to 2021. The salinity maps were predicted by a random forest model. This model combines extensive field soil sampling, satellite remote sensing, and other covariates with high accuracy (especially in regions such as Central Asia, the Middle East, and Xinjiang, China due to the inclusion of many in situ soil samples in these regions).
