Three tall towers are installed at ARM sites: a 60-m triangular tower at the Southern Great Plains (SGP) Central Facility (CF), a 21 m walkup scaffolding tower at the SGP Okmulgee forest site (E21), and a 40-m triangular tower at the North Slope of Alaska (NSA) at Barrow. The towers are used for meteorological, radiological, and other measurements. Instrument systems installed on the towers are listed in section 7, Instrument Details, although only the temperature/relative humidity/vapor pressure (T/RH/VP) measurements made on the SGP CF tower are described in detail. Information on measurements made by the other instrument systems on the towers can be found at individual instrument systems web pages.

三座高观测塔部署于大气辐射测量（ARM）观测站点：分别为位于大平原南部（SGP）中心设施（CF）的60米高三角观测塔、大平原南部奥克穆尔吉森林站点（E21）的21米高可步行攀爬脚手架式观测塔，以及阿拉斯加北坡（NSA）巴罗区域的40米高三角观测塔。上述塔架用于开展气象、辐射及其他类型的观测研究。安装于各塔架的仪器系统详情已在第7章"仪器详情"中列明，不过仅针对大平原南部中心设施塔架上的温度/相对湿度/水汽压（T/RH/VP）观测进行了详细阐述。关于塔架上其余仪器系统的观测相关信息，可查阅各对应仪器系统的官方网页。
