The earlier leaf onset date (LOD) of northern vegetation due to warming has been widely reported, which contributes to enhanced ecosystem productivity. Most studies have focused on warming effects, while the impacts of precipitation on LOD remain unclear. This study examines the role of precipitation frequency in controlling LOD in northern ecosystems, finding that decreased precipitation frequency contributes to earlier LOD in about 10% of the area. The results emphasize the need for a comprehensive understanding of precipitation's impact on LOD for improved projections.
