From: Drought characterization over Indian sub-continent using GRACE-based indices
Monthly GRACE-DSI/CCDI trends using the Mann Kendall trend test and Theil-Sen's slope estimator over major Indian river basins for July, August, and September months. (a) GRACE-DSI trends for July month, (b) CCDI trends for July month, (c) GRACE-DSI trends for August month, (d) CCDI trends for August month, (e) GRACE-DSI trends for September month, (f) CCDI trends for September month. Colormap over the basin represents the slope obtained from TSA, △ represents a significant increasing trend, and ▽ indicates a significant decreasing trend based on the Mann–Kendall test.
