“…LCZ system was previously used to study UHI phenomenon during "ideal days" or on seasonal and annual level (Siu and Hart 2013;Alexander and Mills 2014;Lehnert et al 2015;Fenner et al 2014;Unger et al 2014;Leconte et al 2015;Leconte et al 2017;Skarbit et al 2017;Lehnert et al 2018;Yang et al 2018). Furthermore, LCZ system was applied for mapping (Unger et al 2011;Bechtel and Daneke 2012), development of urban meteorological networks (UMNs) (Lelovics et al 2014;Šećerov et al 2015;Caluwaerts et al 2020), analysis of surface temperatures (Skarbit et al 2015;Gémes et al 2016;Geletič et al 2016a;Geletič et al 2019;Gholami and Beck 2019), outdoor thermal comfort (Kovács and Németh 2012;Puliafito et al 2013;Milošević et al 2016;Unger et al 2018;Kotharkar et al 2019), urban climate modeling (Brousse et al 2016;Geletič et al 2016bGeletič et al , 2018, and urban planning (Middel et al 2014;Perera and Emmanuel 2018). This indicates LCZ system applicability in urban climate studies.…”

A comprehensive analysis of air temperature (T a ) dynamics in "local climate zones" (LCZs) of Novi Sad (Serbia) was based on measurements from 17 stations during 3 years. Hourly changes of T a , cooling rates (CR), heating rates (HR), and urban heat island (UHI) intensity were assessed on seasonal and annual level and during heat wave (HW) and cold wave (CW) periods. Substantial differences are observed for minimum (T min ) and mean temperatures (T mean ) between LCZs. Two-phase nocturnal cooling was recognized with the first cooling phase characterized by intensive LCZ dependent cooling starting at 1-3 h before sunset and lasting until 3-4 h after sunset. The second cooling phase lasts until sunrise and is characterized by less intensive and LCZ nondependent cooling. The most intensive cooling (CR peak ) was observed in first cooling phase of HW and ranged from − 1.6°C h −1 in street canyon (LCZ 2) to − 3.9°C h −1 in forest (LCZ A). Furthermore, a new cooling indicator (CR total ) was introduced. Due to cooling differences, the most intensive UHI of 5.5°C was noticed between LCZs 2 and A at sunset + 1 h during HW. Two-phase diurnal heating was also recognized in LCZs with the first heating phase characterized by intensive LCZ dependent heating starting at sunrise and lasting until 4-7 h afterwards. The most intensive heating (HR peak ) ranged from 2.0°C h −1 in street canyon to 3.0°C h −1 in industrial area (LCZ 8) during HW. The second heating phase lasts until sunset and is characterized by less intensive heating and smaller HR differences between LCZs.

“…Unlike many studies on surface temperature (in Central Europe e.g. Schwarz et al, 2012;Dobrovolný, 2013;Gemés et al, 2016;Geletič et al, 2019;Fricke et al, 2020), only a limited number of empirical studies have been carried out with focus on soil tempera-ture in urban environment. Harman (2003) presented a theory presuming lower average temperature of the soil surface in built-up areas compared to areas outside of housing development.…”

Even though soil temperature in urban environment influences a range of processes, it has been studied rather sparsely in comparison with surface temperature or air temperature. Our research extends the soil temperature observation in Olomouc (Czechia) and uses semi-stationary measurement to describe detailed spatial variability of soil temperature in the area of a medium-sized Central European city. Differences in soil temperature 20 cm below grass-covered surface may exceed 3°C due to soil type, shadow cast by buildings and grass characteristics, which means that the representativeness of the data on soil temperature from a meteorological station within a city may be limited. Further research and a conceptual approach towards the study of soil temperature in urban landscape is needed.

“…Estudos que se utilizaram de outros produtos de Ts, com maior disponibilidade temporal, em conjunto com ZCLs em ambientes urbanos, como os do tipo MODIS, realizaram uma análise da variação sazonal das condições de temperatura (FERREIRA, 2019;FERREIRA & DUARTE, 2018;GELETIČ et al, 2019;HU et al, 2019;MUSHORE et al, 2019;PONGRÁCZ et al, 2018;QUAN, 2019). A baixa disponibilidade temporal do produto ASTER, entretanto, é um desafio para análises como estas, principalmente se o clima da localidade favorecer a presença ou formação de nebulosidade durante todo o ano.…”

As Zonas Climáticas Locais (ZCLs) de uma cidade representam padrões espaciais de elementos da superfície capazes de provocar efeitos no clima urbano. Além da morfologia, os elementos do espaço podem ser analisados por sua temperatura da superfície (Ts), através de produtos de sensoriamento remoto termal satelital, como o AST08, do sensor ASTER. Esta Ts pode ser analisada espacialmente a partir de ZCLs, revelando suas variações espaciais e temporais. Este artigo teve como objetivo analisar a variabilidade espacial e temporal da Ts de imagens ASTER considerando como unidades espaciais ZCLs da cidade de Cuiabá, Brasil. Foram mapeadas as ZCLs de Cuiabá. Obteve-se imagens ASTER de diferentes datas e horários. Comparou-se as ZCLs com a Ts de diferentes condições temporais, sazonais e horárias. Verificou-se variações na Ts em diferentes horas do dia, de manhã e noite. Verificou-se uma variabilidade sazonal na Ts, relacionada a condição climática tropical com inverno seco. A Ts apresenta uma variabilidade espacial e temporal paralela com as ZCLs analisadas.
