A mobile environmental observatory has been established in Greenland which provides almost realtime data from a number of wifi-connected sensors located on the Arctic continent.<\/p>\n

Simultaneous real-time data is collected from Air, Ice, Ground, Rivers and the Marine environment and transmitted to climate scientists working at the Arctic Research Centre<\/a> at Aarhus University in Denmark.<\/p>\n

Many challenges have been overcome to make data available continually, not least the need to generate energy during the Arctic Winter in order to provide instruments with reliable power from batteries which operate at very low temperatures.<\/p>\n

It is hoped that the project’s success will provide a model for global remote environmental data collection, and satellite transmission.<\/p>\n

Remote Mobile Observatory<\/h4>\n

ARC-MO the Arctic Research Centre Mobile Observatory<\/em> is a project to establish two remotely operable containerised weather stations in Greenland. The 2 metre-long wind and solar powered insulated containers are equipped to measure a number of temperature, humidity, chemical, radiation, and biology related data, continuously. The recorded data is averaged and transmitted daily – principally to the Arctic research team at Aarhus University. Data from this station is made available to interested parties at Gios.org<\/a><\/p>\n

Two solar panels on the roof, and two more on the south-facing wall of each container provide plenty of power in the summer. The 380W dual string panels have been chosen for their resistance to the ‘shadow effect’ as snowdrifts frequently obscure part of their surface. In practice the vertical panels can still provide 50% of their rated output when obscured by an 85 – 90cm snowdrift …whereas conventional panels would not harvest energy when covered to a depth of 20cm.\"\"<\/a><\/p>\n

All year round Power<\/h4>\n

During the sunless Arctic winter when the solar output falls to zero, power is provided by a Superwind 353 wind turbine. \u00a0The cut-in wind speed for these units is 3.5m\/sec which would be felt as a gentle breeze (Beaufort F3) …there is no upper wind speed limit. At 12.5m\/s (Beaufort F6) the power output from the 24V turbines is 350W. When the batteries have reached full charge the insulated containers will be warmed by the fins of the turbine regulator heat-sink. Currently each container has one turbine, but two are planned.<\/p>\n

The power installation was designed built and supplied by Danish companies: MG Solar; Solar Polaris and Scanpotec and comprises the following equipment and topography:<\/p>\n
