The surface and tower meteorological instrumentation uses mainly conventional in situ sensors mounted on a tower to measure wind speed, wind direction, air temperature, dew point, and humidity. It also obtains barometric pressure, visibility, and precipitation data from sensors at or near the base of the tower. In addition, a chilled mirror hygrometer is used for comparison purposes.

该地面与塔基气象观测系统主要搭载安装于观测铁塔的常规原位传感器，用以测量风速、风向、气温、露点及湿度；同时通过铁塔基座或其邻近位置的传感器获取气压、能见度与降水数据。此外，该系统还配备冷镜式湿度计（chilled mirror hygrometer）用于比对测量。
