Urban Cold Space Cooling Capacity

et al, 2010, Cheng et al, 2015, Monteiro et al, 2016, Ren et al, 2013), and
polygons identified through statistical methods (Dai et al, 2010, El-Hattab et
al, 2017, Guo et al, 2015, Meng et al, 2018, Pan, 2016, Walawerder et al, 2014,
Zhang et al, 2018).
This study adopts urban cool areas with concentrations of relatively low
temperatures as the main focus of the study is the investigation of variables
playing a role in the mitigation of urban heat islands (Dai et al, 2010, Guo et
al, 2015, Zgang et al, 2018)
The study, which examines İzmir urban area as an example area, aims to
investigate the spatial pattern and features of urban cool areas. The purpose
of the study is to reveal (1) the spatial distribution of spatial pattern of the
urban cool areas and (2) the variables affecting the cooling capacity of urban
cool areas.

Method

The method of the study consists of four stages. The stages are 1) identifying
the scope of the study, (2) producing the data used in the study through the
use of remote sensing techniques, (3) identifying the borders of urban cool
areas, (4) utilizing statistical analysis to measure the relationship between the
cooling capacity of urban cool areas and variables.

1. Scope of the Study
Located in the West of Türkiye, in the coast of the Aegean Sea, the city
of İzmir, is the third biggest city of Türkiye in terms of population. The total
population of the city in 2020 was 4.394.694 (TÜİK, 2020). Surrounded by
mountains, İzmir is a gulf city with a longitude of 37° 45’- 39° 15’ North and
a latitude of 26° 15’- 28° 20’ East. The mountains stand perpendicular to the
sea, which allows the effect of the sea to reach inland and causes the climate
to be milder. The city, characterized with Mediterranean climate, has hot and
dry summers, and mild and rainy winters. The average annual temperature
in the city is around 18°C, reaching 43°C in the summer. Throughout the
city, geographical differences in altitude, height and slope exposure lead to
regional variations in terms of precipitation, temperature and solar exposure.
In the summers, due to the sea breeze in coastal areas, temperatures fall by 1-2
°C. 27% of the mountains covered with shrubs and forests is made up of urban
areas (İzmir Büyükşehir Belediyesi, 2019). The urban area of İzmir is chosen as
the area of study since the urban heat island effect is felt deeply especially
in summer months in İzmir city center, which poses a risk for urban health.
The study covers an area of 25428,6 ha, the urban areas of Menemen, Çiğli,
Karşıyaka, Bayraklı, Bornova, Konak, Karabağlar, Buca, Balçova, Narlıdere and
Gaziemir districts (Figure 1).
