Abstract EN
This study investigated the seasonal variations of daytime urban thermal environment (UTE) based on land surface temperature (LST) in Shenzhen of 2015.
The spatial and temporal adaptive reflectance fusion model (STARFM) was used for retrieving seasonal daytime LST at high spatiotemporal resolution by combining MODIS and HJ-1B LST data.
Next, the relationship between the land cover and daytime in each season was examined.
Finally, daytime LST patterns were classified, and the effects of seasonal variations of high-grade daytime LSTs were analyzed with landscape metrics.
The results showed that (1) the STARFM is capable of generating seasonal daytime LST data at high spatiotemporal resolution.
(2) Daytime LSTs were generally higher in the western parts of Shenzhen in spring and summer.
(3) Daytime LST in each land cover type showed an increasing trend form winter to summer and decreased from summer to autumn.
The highest and lowest daytime LSTs in each season were observed in ISAs and water bodies.
(4) Landscape metrics provided a quantitative method for describing seasonal variations in daytime LSTs, and it was found that seasons influenced the intensity and extent of daytime LSTs in Shenzhen.
These findings may be helpful for urban planners developing regional urban strategies to improve daytime urban thermal comfort conditions.
