Fog is an important water source for many ecosystems, especially in drylands. Most fog‐vegetation studies focus on individual plant scale; the relationship between fog and vegetation function at larger spatial scales remains unclear. This hinders an accurate prediction of climate change impacts on dryland ecosystems. To this end, we examined the effect of fog on vegetation utilizing both optical and microwave remote sensing‐derived vegetation proxies and fog observations from two locations at Gobabeb and Marble Koppie within the fog‐dominated zone of the Namib Desert. Significantly positive relationships were found between fog and vegetation attributes from optical data at both locations. The positive relationship was also observed for microwave data at Gobabeb. Fog can explain about 10%–30% of variability in vegetation proxies. These findings suggested that fog impacts on vegetation can be quantitatively evaluated from space using remote sensing data, opening a new window for research on fog‐vegetation interactions.

卫星观测到雾对植被的积极影响

雾是许多生态系统的重要水源，尤其是在干旱地区。大多数雾生植被研究都集中在单个植物的规模上。在较大的空间尺度上，雾与植被功能之间的关系仍不清楚。这妨碍了准确预测气候变化对旱地生态系统的影响。为此，我们利用光学和微波遥感衍生的植被代理以及在纳米比亚沙漠以雾为主的地区Gobabeb和Marble Koppie两个地点的雾观测，研究了雾对植被的影响。从两个位置的光学数据中发现雾和植被属性之间存在显着的正相关关系。戈巴贝（Gobabeb）的微波数据也观察到正相关。雾可以解释大约10％–30％的植被代理变化。
