Relative air humidity in the year, period 1981-2010

The map shows the mean relative air humidity at 13:30 in the year for the period 1981-2010. For the area-wide calculation the climate stations of MeteoSwiss served as support points. The relative air humidity was interpolated areally at different elevation levels and vertically using gradients. The resulting map has a spatial resolution of 25 m x 25 m. It was used for modelling altitudinal belts of forest vegetation.本地图展示了1981-2010年时段内每日13时30分的平均相对空气湿度空间分布。本次全域计算以瑞士气象局（MeteoSwiss）的气象站点作为支撑控制点。研究人员借助梯度校正方法，针对不同海拔层级与垂直方向开展了相对空气湿度的面域与垂直插值。最终生成的地图空间分辨率为25米×25米，该数据集曾被用于森林植被垂直带谱的建模研究。
