The uncrewed airborne measurement platform MASC-3 (Multi-Purpose Airborne Sensor Carrier) is used to measure the influence of a forested escarpment with differing leaf area indices (LAI) onto the wind field. Data from flight legs between 30 and 200 m above ground with uphill (westerly) wind during summer (July–September) and winter (October–March) seasons between 2018 and 2021 are analyzed. Compared with a low value of LAI, it is found that the mean wind speed acceleration is stronger for a high values of LAI, and the turbulence is enhanced in the lee of the trees in the lowest 20–60 m above ground. During summer with a high LAI, the inclination angle is more clearly defined into an upward motion above the slope and downward motion above the plateau. The results of the airborne dataset fits well into the theoretical and analytical models established in the 1970s and 1980s.

无人机载测量平台 MASC-3（多功能机载传感器载体）用于测量具有不同叶面积指数 ( LAI ) 的森林悬崖对风场的影响。分析了 2018 年至 2021 年夏季（7 月至 9 月）和冬季（10 月至 3 月）季节海拔 30 至 200 m 之间的上坡（西风）飞行航段的数据。与较低的LAI值相比，发现较高的LAI值时平均风速加速度更强，并且在离地最低20~60 m的树木背风处湍流增强。在夏季， LAI较高，倾斜角更清楚地定义为斜坡上方的向上运动和高原上方的向下运动。机载数据集的结果与 1970 年代和 1980 年代建立的理论和分析模型非常吻合。
