A 100 m annual soil salinization dataset from 1985 to 2024 in the Western Songnen Plain, China (model)

In our study, we identified and classified soil salinization degrees in the Western Songnen Plain at 100 m spatial resolution using ground surveys and remote sensing imagery, combined with machine learning algorithms over the period 1985 to 2024.
