ALEX17 Test Site dataset: reference 118m met mast on top of Alaiz ridge

The present dataset is part of the Alaiz Experiment-2017 (ALEX17) which consists of one 118m met masts instrumented with nine measurement levels with booms perpendicular to 360º. Wind speed and wind direction are measured at five levels (118, 102, 90, 78 and 40 m) with wind vanes and cup anemometers, and with sonic anemometers at 118, 78 and 40 meters. Temperature and relative humidity are measured at five levels (113, 97, 81, 38 and 2 m). The dataset has 24 months of wind measurements from July/2017 to July/2019. The experiment report shows the coordinates of all sensors, intrument tilt and boom directions. Both raw data at 20Hz, as well as 10min averages of quality-controlled and tilt corrected data are available.

本数据集属于2017年艾莱兹实验（Alaiz Experiment-2017，缩写ALEX17）。该实验包含一座118米高的气象观测塔（meteorological mast，简称met mast），塔上设有9个测量层级，每个层级均配备垂直于塔身且覆盖360°全向方位的悬臂支架。风速与风向在5个层级（118米、102米、90米、78米及40米）处通过风向标与杯式风速计进行测量；同时在118米、78米及40米处配备超声风速仪。气温与相对湿度在5个层级（113米、97米、81米、38米及2米）处被监测。本数据集包含2017年7月至2019年7月共计24个月的风场观测数据。实验报告中记录了所有传感器的安装坐标、仪器倾斜度以及悬臂支架的方位角。可供获取的数据包含20Hz采样频率的原始观测数据，以及经过质量控制与倾斜校正后的10分钟平均数据。
