Automatic Weather Station

Automatic Weather Stations

The Hong Kong Observatory operates automatic weather stations near Chek Lap Kok to measure the winds around the airport. The remote stations on mountain tops and outlying islands are solar-powered and send the wind data back to the airport using radio waves.  Wind-powered generators have also been installed at a few remote stations to provide power during prolonged cloudy condition.
