China will build the world's highest unmanned automatic weather information station at an altitude of 5,300 metres on the peak of Mt Everest to acquire 'error-free climatic data', the state media reported on Tuesday.

The station will be completed within the year to record meteorological data like temperature, humidity, air pressure, rainfall, wind speed and ultraviolet radiation, the director of the monitoring networks of the Tibet Weather Bureau, Wang Jianshe, said in Lhasa, Tibet's capital.

Currently the unpredictable weather in Mt Everest (Qomolangma in Chinese) area is monitored by a station, 90 km away, raising the possibility of errors in accuracy of the information collected.

Wang said the station would help provide long-term and accurate weather consultations. It would help build a climate database for regional weather analysis over long periods, Xinhua news agency reported.

The station was part of the local weather authorities' drive to build an automatic weather monitoring network with 41 stations across Tibet autonomous region, he said.

The network would cost 27.35 million yuan (US $3.3 million) to complete. Data would be collected and recorded automatically, and the stations would be linked by satellite or cable to share information for research and analysis, Wang said.
