Air temperature and SVF measurements were conducted in a green Singapore estate, One-North, from November 1, 2007 to March 31, 2008. The field measurement results show that daytime air temperature difference between dense greenery area and less greenery area is 2.4 K and the nighttime air temperature difference is 1.1 K. The temperature maps study provides a clear picture on the air temperature distribution across the One-North estate and concludes that parks or clusters of trees are able to maintain both daytime and nighttime air temperature at a cool level. Statistical analysis was conducted to analyze the correlation between air temperature and SVF. During daytime, there is a significant and good correlation between air temperature and SVF. The higher the SVF, the higher is the air temperature. Trees reduce the sky openness and provide shading to the environment. At nighttime, there is a weak correlation between air temperature and SVF. Thus, there is no adverse impact, i.e., reduction of nighttime net long-wave loss, due to the reduction of SVF by trees. © 2010 ASCE.||Source Title:||Journal of Urban Planning and Development||URI:||http://scholarbank.nus.edu.sg/handle/10635/46028||ISSN:||07339488||DOI:||10.1061/(ASCE)UP.1943-5444.0000014|
