A Field Measurement of Temperature Distribution in Johor Bahru, Malaysia: A Preliminary Study of Mitigation Measures for Urban Heat Island in the Tropics

摘要

The nocturnal temperature difference between the urban and surrounding areas in the city of Johor Bahru recorded a maximum of 4°C in the sunny day. The maximum nocturnal air temperatures were recorded in relatively densely built-up areas, such as the city center, large housing estates and industrial areas. It was found that relatively large open spaces (green areas) scattered in between the built-up areas may have created low air temperature areas and divided the UHI of the city.
