A mobile observatory powered by sun and wind for near real time measurements of atmospheric, glacial, terrestrial, limnic and coastal oceanic conditions in remote off-grid areas

Climate change is rapidly altering the Arctic environment. Although long-term environmental observations have been made at a few locations in the Arctic, the incomplete coverage from ground stations is the main limit to observations in these remote areas. Here we present a multi-purpose mobile observatory (ARC-MO) powered by sun and wind, enabling near real time measurements in the air, ice, land, rivers and ocean in remote off-grid areas. Two test units were constructed and placed in Northeast Greenland where they have collected data from cabled and wireless instruments in the environment since late summer 2021. The two units can communicate locally via WiFi (units placed 25 km apart) and transmit near-real time data globally over satellite. Data are streamed live and accessible from (https://gios.org). The cost of one mobile observatory unit is c. 304.000€. These test units demonstrate the possibility for integrative and automated environmental data collection in remote coastal areas and could serve as models for a proposed global observatory system

气候变化正迅速改变北极环境。尽管在北极部分地区已进行了长期的环境观测，但地面观测站的不完整覆盖仍是这些偏远地区观测的主要限制因素。本报告展示了由太阳能和风能驱动的多功能移动观测站（ARC-MO），该观测站能够实现对偏远无电网区域的空气、冰面、陆地、河流和海洋的近实时测量。两个测试单元已在格陵兰岛东北部建立，并自2021年晚夏以来，从环境中的有线和无线仪器收集数据。这两个单元可通过WiFi进行本地通信（单元之间相距25公里），并通过卫星向全球传输近实时数据。数据实时传输，并通过（https://gios.org）提供访问。一个移动观测站单元的成本约为304,000欧元。这些测试单元展示了在偏远沿海地区进行综合和自动化环境数据收集的可能性，并可作为拟议的全球观测系统模型的范例。
