“…LST changes over a specific area are highly variable and also sensitive to many parameters such as topography, altitude, slope, vegetation cover, type of vegetation, soil moisture, roughness, surface albedo and absorptivity, which are closely related to LULC type ( Harmay et al, 2021 ; Portela et al, 2020 ). Therefore, LST anomalies during the lockdown period may be sensitive to several factors beyond the effect of less anthropogenic aerosols and pollutants in the urban areas.…”

“…forests, agricultural lands) and water bodies were associated with lower temperatures ( Chen & Lin, 2021 ). Thereby, characteristics of urban surfaces are the main driving factors for either increment or mitigation of LST due to alternation in albedo, emissivity, thermal conductivity and radiative fluxes ( Fitria et al, 2019 ; Portela et al, 2020 ). Urbanization also alters the LULC, and consequently, the UHI is significantly higher in cities leading to detrimental effects on human health associated with heat stress ( Patz et al, 2005 ).…”

The outbreak of SARS CoV-2 (COVID-19) has posed a serious threat to human beings, society, and economic activities all over the world. Worldwide rigorous containment measures for limiting the spread of the virus have several beneficial environmental implications due to decreased anthropogenic emissions and air pollutants, which provide a unique opportunity to understand and quantify the human impact on atmospheric environment. In the present study, the associated changes in Land Surface Temperature (LST), aerosol, and atmospheric water vapor content were investigated over highly COVID-19 impacted areas, namely, Europe and North America. The key findings revealed a large-scale negative standardized LST anomaly during nighttime across Europe (–0.11°C to –2.6°C), USA (–0.70°C) and Canada (–0.27°C) in March–May of the pandemic year 2020 compared to the mean of 2015–2019, which can be partly ascribed to the lockdown effect. The reduced LST was corroborated with the negative anomaly of air temperature measured at meteorological stations (i.e. –0.46°C to –0.96°C). A larger decrease in nighttime LST was also seen in urban areas (by ∼1–2°C) compared to rural landscapes, which suggests a weakness of the urban heat island effect during the lockdown period due to large decrease in absorbing aerosols and air pollutants. On the contrary, daytime LST increased over most parts of Europe due to less attenuation of solar radiation by atmospheric aerosols. Synoptic meteorological variability and several surface-related factors may mask these changes and significantly affect the variations in LST, aerosols and water vapour content. The changes in LST may be a temporary phenomenon during the lockdown but provides an excellent opportunity to investigate the effects of various forcing controlling factors in urban microclimate and a strong evidence base for potential environmental benefits through urban planning and policy implementation.

“…While each city has its own unique combination of climate, geography, and internal structure, some common patterns can be observed. Hotspots are often found in industrial parts of cities, where waste heat, the use of dark construction material and absence of vegetation can result in high SUHI intensities 45 . For example, in New York particularly high values of 18 can be observed South of Newark, where the international airport, a railroad and other industrial facilities are located (Fig.…”

Surface temperatures are generally higher in cities than in rural surroundings. This phenomenon, known as surface urban heat island (SUHI), increases the risk of heat-related human illnesses and mortality. Past global studies analysed this phenomenon aggregated at city scale or over seasonal and annual time periods, while human impacts strongly depend on shorter term heat stress experienced locally. Here we develop a global long-term high-resolution dataset of daytime SUHI as urban-rural surface temperature differences. Our results show that across urban areas worldwide over the period 2003-2020, 3-day SUHI extremes are on average more than twice as high as the warm-season median SUHI, with local exceedances up to 10 K. Over this period, SUHI extremes have increased more rapidly than warm-season medians, and averaged worldwide are now 1.04 K or 31% higher compared to 2003. This can be linked with increasing urbanisation, more frequent heatwaves, and greening of the earth, processes that are all expected to continue in the coming decades. Within many cities there are hotspots where extreme SUHI intensity is 10 to 15 K higher compared to relatively cooler city parts. Given the limited human adaptability to heat stress, our results advocate for mitigation strategies targeted at reducing SUHI extremes in the most vulnerable and exposed city neighbourhoods.

“…Urban living environment deprivation is a multidimensional phenomenon that results from the complex interaction of socio-demographic, socio-economic, and eco-environmental factors.The urban induced adverse eco-environmental impacts such as decreasing vegetation cover ( Du et al, 2019 ; Gui, Wang, Yao, & Yu, 2019 ; Sussman, Raghavendra, & Zhou, 2019 ; Yao, Cao, Wang, Zhang, & Wu, 2019 ), increasing impervious surfaces and the concomitant rise in land surface temperature ( Li, Zhang, Mirzaei, Zhang, & Zhao, 2018 ; Portela, Massi, Rodrigues, & Alcântara, 2020 ; Sejati, Buchori, & Rudiarto, 2019 ; Sultana & Satyanarayana, 2020 ; Zhang, Estoque, & Murayama, 2017 ; Fu & Weng, 2016 ; Yang, Sun, Ge, & Li, 2017 ; Jiang, Fu, & Weng, 2015 ; Fonseka et al, 2019 ; Bian, Ren, & Yue, 2017 ; Guo et al, 2015 ; Zhang & Sun, 2019 ; Arulbalaji, Padmalal, & Maya, 2020 ); socio-demographic factors such as the high density of population and households (HHs) negatively influences urban living environment deprivation ( Niu, Chen, & Yuan, 2020 ; Musse et al, 2018 ). The urban living environment deprivation leads to deterioration of health and human comfort in cities that increases the susceptibility of infectious diseases ( EPA, U., 2008 ).…”
