“…Four street canyons in Yogyakartai.e., Urip Sumoharjo Street (US), C. Simanjuntak Street (CS), Palagan Tentara Pelajar Street (PT), and Agus Salim Street (AS),were selected based on the street orientation, façade materials, green area, building density and height. Ivan & Benedek (2017), Paramita & Suparta (2019) and Ursu (2019) mentioned that built-up area, green area, building density and height affect the land surface temperature and microclimate. The street canyons are situated at the latitude of 7 o 48'5"S and the longitude of 110 o 21'52"E that belongs to hot-humid climates (Koppen Aw).…”

This paper aims to study a microclimate model for predicting the role of façade materials to the Canopy Layer Heat Island. ENVI-met was selected to model the microclimate of four street canyons in Yogyakarta, which vary in façade materials, street orientation, and land cover. Three to four-day field measurements in each canyon were intended to obtain microclimate data at pedestrian level, wind speed and orientation at the boundary layer for simulation input and validation. The validation study confirms the accuracy of ENVI-met simulations in predicting air temperature and relative humidity when the initial wind speed at the boundary layer is > 1.5 m/s. These input data affected on the simulation results. However, the "comparison" feature offers a facility to analyze the modification in the air temperature and mean radiant temperature in the street canyon due to higher thermal transmittance and higher surface albedo façade materials. The results show that street orientation, big trees along the street and sky view factor significantly affect the pattern of air temperature modified by the increasing thermal transmittance and albedo of the façades.

Using MODIS and Landsat LST images, the present paper advances a series of results on the characteristics of the surface heat island (SUHI) of Bacău City (Romania) during the warm season (April to September) for a period of 20 years (2001–2020). At the same time, given their higher temporal resolution and their availability for both day and night, MODIS LST was used to understand the spatial features of the SUHI in relation to land use. In this way, a total of 946 MODIS Terra and 483 Landsat satellite images were used to outline the main LST characteristics of the days with clear sky in this middle-sized city in northeast Romania. In order to analyze MODIS LST changes in relation to land use changes in the period 2001–2018, we used the standardized CORINE Land Cover datasets. With the help of the Rodionov test, we were able to determine the geometry and intensity of the SUHI. During the day, the spatial extension of the SUHI reaches its maximum level and is delimited by the isotherm of 31.0 °C, which is 1.5–2.0 °C warmer than the neighboring non-urban areas. During the night, the SUHI has a more regulated spatial extension around the central area of the city, delimited by the 15.5 °C isotherm with LST values that are 1.0–1.5 °C warmer than the surrounding non-urban areas. Additionally, from a methodological point of view, we highlight that resampled MODIS and Landsat images at a spatial resolution of 500 m can be used with confidence to understand the detailed spatial features of the SUHI. The results of this study could help the elaboration of future policies meant to mitigate the effects of urbanization on the SUHI in an era of increasing air temperatures during summer.
