Contrasting determinants of land surface temperature in three megacities: Implications to cool tropical metropolitan regions

Sustainable Cities and Society, Journal Year: 2023, Volume and Issue: 92, P. 104505 - 104505

Published: March 5, 2023

Megacities in tropical regions are among the urban centers most vulnerable to increasingly intense heatwaves. However, complex interactions between characteristics and thermal environments yet be fully understood. Here, we investigated relationship land surface temperature (LST) for three megacities savannah climate zone, Chennai, Dhaka, Kolkata. LST values were retrieved from Landsat 8 data, features constructed using digital models, building footprints, satellite imagery. Model-agnostic approaches adopted analyze impacts of on LST. The boosted regression tree (BRT) model was used capture nonlinear effects six important factors changes. dominant influencing normalized difference built-up index, albedo, vegetation index. Building roofs, roads, other hardscapes with high-albedo materials preferred alleviating heat island effect Dhaka placement parks woody an area larger than 0.6 ha produced effective cooling effect. In Chennai Kolkata, policies increase sky view factor recommended. application BRT integrated data provides unique insights resilience planning.

How does 2D and 3D of urban morphology affect the seasonal land surface temperature in Island City? A block-scale perspective

Ecological Indicators, Journal Year: 2023, Volume and Issue: 150, P. 110221 - 110221

Published: April 8, 2023

The global climate warming caused by urbanization has significantly affected the urban environment. Whilst land surface temperature (LST) is an important factor reflecting temperature, previous research on LST mostly focused two-dimensional (2D) factors and rarely mentioned about role of three-dimensional (3D) factors, particularly variation characteristics island cities. Therefore, this study examined seasonal analyzing impact 2D 3D morphology different block types in Xiamen Island. main results are as follows. First, compact low layer (CL), a type with higher density low-rise buildings, any season. Under same (BD), average height (BH), lower LST. Second, among normalized difference vegetation index (NDVI) was for cities to reduce LST, especially summer, while built-up (NDBI) opposite. Different from cities, we found positive correlation between modified water body (MNDWI) autumn winter. Third, sky view (SVF) positively correlated building fluctuation (BF) negatively correlated. SVF, worse radiation shielding effect buildings. On contrary, BF, undulation, better shielding. These findings should provide some quantitative insights future construction planning which can be used improve thermal environment support sustainable development

In this paper, the spatial patterns of urban form (e.g., 2D and 3D characteristics) from 2000 to 2020 in Jakarta are assessed interdependent relationships between built-up volume environment examined. experienced rapid land expansion 19%, 483 km2 574 but with moderate volumetric at 4%, 23.6 × 108 m3 24.5 2020. The inverse S-shaped function revealed that density declined city center surrounding areas Jakarta. Urban area expanded outward a much faster rate than upward, reflected by D value, i.e., radius central area. value remained around 17 km for grew substantially 28 50 during same period. Furthermore, structural equation model (SEM) analysis showed that, while increases associated green space, path coefficient 0.620, they also linked worsening air pollution heat islands, statistically significant coefficients 0.304 0.440, respectively.
