Table 2 Climate classification and dryland subtypes based on the Aridity Index.
From: A global dataset of remote sensing-based soil critical point and permanent wilting point
Classification | Aridity Index (AI) |
|---|---|
Hyper-arid | AI < 0.05 |
Arid | 0.05 ≤ AI < 0.2 |
Semi-arid | 0.2 ≤ AI < 0.5 |
Dry Subhumid | 0.5 ≤ AI < 0.65 |
Humid | AI ≥ 0.65 |
