在伊比利亚半岛东海岸的巴伦西亚地区选择了四个不同的山区地点进行雾水收集研究。 2004 年的数据是通过仪器组获得的，该仪器组主要由被动圆柱形雾水收集器、雨量计、风向和风速传感器以及温度和湿度探头组成。还发现了针对该特定集合的近似数据缩减技术，以消除雾水测量中的同时雨水成分。主要结果表明，雾水收集在该地区具有巨大潜力，特别是对于南部地区。南部地区的年雾水产生率可高达 7.01/m(2)/天，而北方地区某一地点的雾水产生量为 2.01/m(2)/天。夏季雾产水量最高为4.61/m(2)/天，属于较大值。除夏季外，产生大量水量的雾气本质上与降雨有关。还检查了每小时雾收集的频率，以显示夏季明显的每日周期，表明在此期间形成了地形雾。最后，对风进行了分析，以确定最适合雾收集器排列的方向。 (c) 2007 Elsevier B.V. 保留所有权利。
Four different mountainous locations were selected in the Valencia region, East coast of the Iberian Peninsula, for fog water collection studies. Data for 2004 were obtained by means of an instrument ensemble consisting essentially of a passive cylindrical fog water collector, a raingauge, a wind direction and velocity sensor and a temperature and humidity probe. An approximate data reduction technique was also found for this specific ensemble to eliminate the simultaneous rain water component from the fog water measurements. Main results indicate that fog water collection holds significant potential in this region, and especially for southern locations. Annual rates of fog water yield can be as high as 7.01/m(2)/day in the southern locations, in contrast to 2.01/m(2)/day collected at one site in a nor-them location. The highest summer fog water yield was 4.61/m(2)/day, a relatively large value. Except for the summer period, fog episodes delivering sizeable water volumes are inherently coupled to rainfall. Hourly frequencies of fog collection were also examined to show a distinct daily cycle in summer, denoting orographic fog formation during this period. Lastly, winds were analysed to resolve the most suitable directions for fog collector alignment. (c) 2007 Elsevier B.V. All rights reserved.
