Fig. 1: Temporal dynamics of the response ratio of flash droughts at different onset times.
From: Gross primary productivity is more sensitive to accelerated flash droughts
a Trends of the percentage of 1-, 2-, 3-, 4-, and 5-pentad onset flash droughts resulting in negative saGPP relative to all flash droughts with saGPP responses across five different datasets. b Temporal trends of the percentage of different onset flash droughts resulting in negative saGPP relative to all flash droughts with saGPP responses across 21 regions, based on the mean results from GLEAM, MERRA2, Noah, CLSM, and VIC, evaluated by the magnitude of Sen’s slope. Bars with slashes indicate trends that are statistically significant at the 0.05 level. The linear annual trends are estimated using Sen’s slope estimator, and statistical significance is determined by the Mann-Kendall test for the study period (2001–2018).
