Cool Island Intensity

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.
