METEOROLOGICAL TOWER DESIGN FOR SEVERE WEATHER AND REMOTE LOCATIONS

We have developed a robust meteorological tower for deployment in locations with extreme conditions and for applications that require relatively maintenance-free structures. The basic design consists of a triangular base with two horizontal rails on each side, and uprights at the triangle vertices for various instrument configurations. The fabrication materials include 6061-T6 aluminum pipe (schedule 40 or 80), and cast aluminum connectors. The design is self-supporting, but may be guyed. Advantages of the design compared to conventional towers include easy assembly, readily available materials, easy adjustment for rugged location or terrain, transportable components by backpack, helicopter, boat, snowmobile, ATV or alternate method, and no need for concrete. Like all structures, the design is vulnerable to snow creep in deep-snow environs, but judicious site selection will mitigate this issue. We deployed these stations with minor variations in design in Alaska and Colorado, USA and on Baffin Island, Nunavut, Canada. The towers have survived relatively severe conditions in terms of cold temperature, wind, rime, and snow deposition. Locations have included subalpine, alpine, and arctic maritime environments. Regular data transmission has been achieved via satellite modem and satellite transmitter. We discuss design and installation.
