Details	:	GPS signals experience propagation delays in the ionosphere and troposphere, partially resulting from the existence of water vapour. Through analysing the delays, the content of water vapour known as Precipitable Water Vapour (PWV) in the atmosphere could be derived for weather forecast. The Hong Kong Observatory (HKO) has been operating a system that collects GPS data from the ground stations in Hong Kong and Guangdong for monitoring the evolution of rainstorms in the region. The speaker, Mr. WOO Wang-chun, would like to share with us how the HKO makes use of such information for monitoring and forecasting the weather. Apart from weather forecasting, HKO has also employed the GPS technology to monitor the crustal movement. Through continuous monitoring of the movement of GPS station at Tate's Cairn since 2006 and comparison of the measurement results among other locations in Hong Kong, it is found that this area has been steadily drifting east-southeastward at an average speed of about 3cm a year. The speaker, Mr. HUI Tai-wai, David, would like to share with us their approaches and result of the project.
