Air pollution dynamics: the role of meteorological factors in PM10 concentratio...
Girotti, Carolina; Kowalski, Luiz; Silva, Tiago; Correia, Ezequiel; R. Prata Shimomura, Alessandra; Akira Kurokawa, Fernando; Lopes, AntónioAir pollution is a major health problem in urban areas, influenced by traffic and atmospheric conditions. This study investigates the relationship between meteorological factors—wind direction, wind speed, boundary layer height, and atmospheric stability conditions —street trees, and PM10 concentration in three urban canyons: Avenida da Liberdade and Estrada de Benfica in Lisbon, and Marginal Tietê in São Paulo...

Modeling the influence of summer sea and estuarine breezes on heat stress in Li...
Reis, Cláudia; Oettl, Dietmar; Lopes, António; Nouri, A. Santos; Vasconcelos, JoãoIn this study, the influence of the Tagus river and Atlantic Ocean breezes in a Mediterranean city (Lisbon) on outdoor thermal comfort was analyzed during the thermal summer days. Hourly wind fields were modeled using the GRAMM-SCI software, initialized with ERA5 reanalysis data. The Universal Thermal Climate Index (UTCI) was calculated for 80 weather stations across the city. Additionally, the UTCI anomalies (...
Heat stress mitigation by exploring UTCI hotspots and enhancing thermal comfort...
Silva, Tiago; Matias, Márcia; Girotti, Carolina; Vasconcelos, João; Lopes, AntónioHeat stress mitigation actions must be carefully planned in order to achieve efective outcomes. By integrating urban planning guidelines with urban climate knowledge, substantial benefts can be achieved for the community. In Lisbon, the study area, urban planning guidelines are strict in relation to the tree species which should be used for planting. This study examined these species environmental contributions...
Comparative study of microclimatic variables in industrial and residential area...
Arruda, Angela Maria de; Lopes, António; Masiero, ÉricoThe efects of urban heat islands (UHIs) have intensifed with increasing urbanization and industrialization of natural environments. This study aims to identify the formation of UHIs in an industrial district by analyzing possible correlations between the variables that infuence the urban microclimate. Data were collected in situ over 15 days, focusing on air temperature and relative humidity in both an industri...
Climate walking: A comparison study of mobile weather stations and their releva...
Silva, Tiago; Ramusga, R.; Matias, Márcia; Amaro, J.; Bonifácio, Ana; Reis, Cláudia; Chokhachian, A.; Lopes, G.; Almeida, A.; Frazão, J.Microclimate conditions affect the outdoor urban way of life for humans. These conditions directly impact people’s health and well-being, such as access to medical care or a healthy lifestyle. Human thermal comfort is paramount for people’s health, both physical and mental. In this paper, the study compares two microclimate mobile weather stations (MWS) based on a set of users’-based assessment criteria (usabil...
Microclimate simulation and lichen-based validation analyzing street trees' imp...
Girotti, Carolina; Matos, Paula; Shimomura, Alessandra R. Prata; Kurokawa, Fernando Akira; Correia, Ezequiel; Lopes, AntónioThis study investigates the impact of street trees on air pollutant concentrations, specifically NO₂ and PM10, in urban environments using computational fluid dynamics (CFD) simulations with ENVI-met software. The study explores how different levels of tree cover influence the dispersion of atmospheric pollutants, focusing on three scenarios: current tree cover, complete removal of street trees, and a 50 % redu...
LCZ4r package R for local climate zones and urban heat islands
Anjos, Max; Medeiros, Dayvid; Castelhano, Francisco; Meier, Fred; Silva, Tiago; Correia, Ezequiel; Lopes, AntónioThe LCZ4r is a novel toolkit designed to streamline Local Climate Zones (LCZ) classification and Urban Heat Island (UHI) analysis. Built on the open-source R statistical programming platform, the LCZ4r package aims to improve the usability of the LCZ framework for climate and environment researchers. The suite of LCZ4r functions is categorized into general and local functions (https://bymaxanjos.githu b.io/LCZ4...
Projeto Pontes Atlânticas: uma ponte entre os estudantes de fisioterapia da lus...
Leão, Carla; Neves, Maria Ana; Ribeiro, Andrea; Lopes, António; Pedro, Márcia; Sousa, José Luís; Pereira, Ângela; Graça, Maria; Vicente, SóniaA Etapa I do projeto de internacionalização Pontes Atlânticas, do Núcleo Académico de Fisioterapia (NAFisio) da Rede Académica das Ciências da Saúde da Lusofonia (RACS), iniciado no ano letivo 21/22, com segunda edição em 22/23, promove a partilha de perspetivas sobre o contexto educativo e profissional da Fisioterapia entre estudantes de diferentes instituições de ensino superior (IES) membros da RACS. Através...
Climate walking and linear mixed model statistics for the seasonal outdoor ther...
Silva, Tiago; Reis, Cláudia; Braz, Diogo; Vasconcelos, João; Lopes, AntónioTo measure urban outdoor pedestrian thermophysiological comfort mobile roving missions were conducted in all seasons of the year during the day and at night. Six routes were chosen, representing areas of the city with varying urban morphological layouts. The thermal comfort conditions were analysed using the Local Climate Zone spatial scale. This enabled the identification of typologies of areas where pedestria...
