An urban park located in a densely built area of Western Athens, Greece is monitored. Temperature data from 15 urban and suburban stations are also used to perform comparative analysis at the city level. The park presents an important temperature inhomogeneity during day and night due to the variable radiative cooling capacity and shading potential between its various zones. Average nocturnal Cool Island Intensities (CII) against the reference urban stations varied between – 0.7 K to – 2.8 K while during the daytime the maximum CII was between -0.2 to -2.6 K.
Increase of energy consumption and deforestation within cities has already begun raising average urbantemperature: this phenomenon is called urban heat island (UHL). A phenomenon in which there is aconsistent increase in urban air temperature and a decrease in the relative humidity as compare to ruralareas. Generally, research on this topic has been based on observational, theoretical and modelingapproaches.
Urban development is unavoidable as the result of country’s economic growth. Without a careful planning, a city may cause environment destruction. Singapore is known to have the best environmental quality in the world. However, in the previous research on
