Monitoring Hong Kong's Urban Heat Island

Hong Kong's urban areas have been getting hotter and more uncomfortable, due to the combined effects of urbanisation and the greenhouse effect of global warming. However, the influence of urban development on these higher temperatures is much greater than the effects of long-term global climate change. The researchers of the Department of Land Surveying and Geo-Informatics, Hong Kong Polytechnic University have been monitoring Hong Kong's urban heat island using satellite and aerial images for over ten years in order to estimate temperatures and heat emissions over the city. Thermal satellite images, from NASA's Terra and Landsat satellites as well as the Chinese satellite HJ1B, are captured on hot summer days and nights to give an overview of temperatures across Hong Kong. Helicopter-borne thermography was carried out in August 2013 to provide additional, more detailed thermal information on streets and buildings to help researchers to build 3-dimensional thermal models. These can indicate how different building design, materials and planning practices affect heat island formation. The satellite and helicopter-borne thermal images are supported by a large field team on the ground at the imaging time, measuring surface and air temperatures for image calibration and accuracy assessment. By integrating Global Climate Models with thermal satellite images, the research team predicts an increase of 1-2°C for the core urban areas of Hong Kong by 2040.

Exhibition information is provided by Professor Nichol, Janet Elizabeth and her research team of Department of Land Surveying and Geo-Informatics, The Hong Kong Polytechnic University. It will be on show from 28 June 2014.
