China's first ultra-low temperature automatic weather station in the South Pole stable operation

[China Instrument Network Instrument R&D] Recently, a new generation of ultra-low temperature automatic meteorological station independently researched and developed by the Institute of Polar Meteorology of the Chinese Academy of Meteorological Sciences has been successfully tested in the Antarctic. This indicates that China has become the third country capable of conducting continuous automatic meteorological observations in the ultra-low temperature region of Antarctica after Australia and the United States.

The temperature in the Antarctic region is extremely low and it is very difficult for environmental monitoring. According to reports, the lowest temperature in the Antarctic region can reach -89.2°C, and the wind speed can reach 100m/s. However, Antarctica is a very special region and is closely related to the global environment. Through the monitoring of the Antarctic region, it can be used for research including China. Global changes, including weather and climate change, are expected to provide useful information for the prediction of mid- and long-term climate change, which is of far-reaching significance.

In the process of environmental monitoring, ultra-low temperature automatic weather stations need to use various sensors such as wind speed, wind direction, snow surface infrared temperature, solar radiation, air temperature, air pressure, and relative humidity. At the same time, data acquisition systems and information distribution systems are also extremely important. In such a severe temperature situation, how these instruments can operate successfully has become an important issue.

Since 2010, the Institute of Polar Meteorology of the Chinese Academy of Meteorological Sciences has invested a large amount of human, material, and financial resources to start testing at -40°C. In 2014, it expanded to -60°C and achieved success. Later, the experiment extended to the highest Antarctic ice sheet. The two trials in 2015 and 2016 all failed. Finally, the R&D team successfully developed a variety of equipment and systems in 2017. After more than one year of testing, it successfully verified the data recorded in the data. Real reliability.

According to reports, the polar temperature (-60°C) automatic weather station developed by the Polar Chamber has been installed at Taishan Station and Grove Mountain in Antarctica, providing an important basis for the analysis of polar weather and climate change.
