Spatiotemporal variations of extreme events and their effects on vegetation growth in the Northern permafrost regions during 1982-2022

The permafrost regions of the Northern Hemisphere are increasingly experiencing frequent and intense extreme events, which may significantly impact the vegetation growth. However, the effects of extremes on vegetation are often overlooked, leading to an underestimation of their impacts on vegetation. Here we provide a comprehensive analysis of the spatiotemporal variations of extreme events in the Northern permafrost regions from 1982 to 2022, as well as the responses of vegetation growth to these changes in growing-seasons.

北半球多年冻土区正日益遭遇愈发频繁且强度更高的极端事件，此类事件可能对植被生长造成显著影响。然而，极端事件对植被的影响往往被忽视，进而导致对其植被影响效应的评估存在低估。本数据集提供了1982至2022年北半球多年冻土区极端事件的时空变化特征，以及生长季植被生长对这些极端事件变化的响应规律的综合分析。
