What is it about?
This research examines the spatial formation of the daytime Surface Urban Cool Island (SUCI) effect of Erbil city in Iraq, as a case study of cities in semi-arid climates. The results indicate that densely built-up areas, had lower LST acting as cool islands, compared to the non-urbanized area around the city. A very strong inverse relationship is evident between surface temperature and wetness index (r = −0.9; p < 0.01). This study shows that during the dry season in some cities, such as Erbil, the surface wetness is the main determinant of the UCI effect, and not vegetation cover.

Why is it important?
- Densely built-up areas and green areas, had lower LST acting as cool islands. - Open spaces and new low-density housing developments, experienced higher LST. - Surface Urban Cool Island Intensity (SUCII) of the city ranged from 3.5 to 4.6 °C. - A strong inverse relationship is evident between surface temperature and wetness. - In some cities such as Erbil the surface wetness is the main determinant of the UCI.
Perspectives
It is focused on LST of Erbil city as a case study of cities in semi-arid climate. In the first time it use TC instead of NDVI and NDWI. From 2016 to 2018 it cited 18 times.
