What is it about?
This research was conducted to evaluate the variation of the urban heat island (UHI) effects in the planned city of Putrajaya over one year. Putrajaya, the administrative capital of Malaysia, is known for its meticulous town planning. The main observations are temperature variation, the changes in wind speed, the percentage of relative humidity, and subsequently, the intensity of UHI in the research area.

Why is it important?
Putrajaya Corporation Complex Precinct 3 (P3) and Precinct 9 (P9) are located in the central business district (CBD) and residential areas, respectively. These two places represent UHI's effects on CBD and residential areas. Ultrasonic anemometers, which measure three components of wind velocities and temperature, were employed to analyze temperature and wind patterns.
Perspectives
I hope this paper highlights the importance of HUI in our daily activities as our results indicate high temperatures during the day cause human heat stress and discomfort. The UHI intensities of the city are within the range of temperature differences of 2 to 3 °C. Working with knowledgeable co-authors was a great pleasure, and I have had long-standing collaborations with the lead author Prof. Harun.
