“…In fact, the marked decrease of MRT in the scenarios with vegetation is due to both the increase of shaded area and the presence of soil (Default Soil) in the traffic island, as already observed in the literature [28,42,43]; moreover, the difference of 4.62 • C for MRT between the current and the modified scenario is due to the removal of 40 Pinus pinea L. and the introduction of 70 new trees with higher leaf density and crown width. As already observed in the literature [34], Pines do not change the MRT index considerably compared to other species due to their height development; • the extent, continuity and compactness of the vegetation cover along Corso Trieste are certainly a factor that influences the overall positive effect of the vegetation. Increasing the compactness of the vegetation, in fact, in the modified scenario, there is a further improvement of the microclimatic conditions and a more efficient mitigation action; • it is possible to observe that the differences found between the current scenario with Pinus pinea L. and the modified scenario are due to the increase in vegetation, equal to 2040 m 2 , with LAD greater than 1.00 m 2 m −3 , so it is possible to conclude that the magnitude of the reductions of T air , MRT and PMV is dependent on the crown coverage [28,[44][45][46].…”

“…In this perspective, an 18-m-high tree with a crown width of 7 m and height of 6 m was chosen, in order to allow ventilation below it. In the current scenario, the height of the old Pinus pinea L. allows a wide ventilation within the canyon [30][31][32][33][34]-a prerogative that must be considered in the planning and renovation phase. A modified scenario where a partial renewal of the existing Pinus pinea L. was assumed.…”

This study carries out a quantitative analysis of the impact on microclimate (air temperature and thermal comfort) of a row of 165 historical Pinus pinea L. located in a central neighbourhood of Rome (Italy). The analysis starts from a qualitative general analysis on the stressful conditions leading to tree decline in the urban environment especially during extreme climate change phenomena. Subsequently, the effects of planting new types of trees are assessed using ENVI-met, a 3D prognostic non-hydrostatic model for the simulation of surface-plant-air interactions. Results, obtained by simulating three different scenarios in which the trees are first removed and then modified, show that a gradual renewal of the existing trees, based on priority criteria of maturity or senescence, vegetative and phytosanitary conditions, efficiency of ecosystem services and safety for citizens, has positive effects on thermal comfort. By integrating current results and scientific literature, the final aim of this work is to provide stakeholders with a strategic and systemic planning methodology, which, based on the innovative integrated use of tree management and modelling tools, may (i) enhance the benefits of greening in a scenario of climate change and (ii) lead to intervention strategies based on complementarity between conservation of existing trees and tree renewal.

“…Due to the location of the park in the city center, it is somewhat affected by the northern mountains and the southern desert therefore, the city's average temperature in uences its microclimate. As well, the site offers a variety of activities, including chatting, sports, and playing music in the park that all these things help to justify the choice of this site (Karimi et al, 2020).…”

Regarding the significant impact of visibility, landscape, and thermal comfort on the presence of users’ attendance in urban parks, there is a severe interest in studies on the amount of visibility and the outdoor thermal comfort especially in a district with hot summers. this research, after investigating the shafagh park based on space laws and the relationship between park spaces with each other in terms of accessibility and visibility to achieve the effect of plants, then, based on the obtained data, the role of plants in evaluating thermal comfort conditions in the park space was investigated and finally, their relationship with each other has been examined. results have revealed that, plants have an undeniable role in improving the conditions of thermal comfort and visual visibility and user movement in spaces, so that, the best points in terms of thermal comfort, had a favorable view and perspective, while, areas of the park that did not have good visibility and landscape did not experience favorable conditions in terms of thermal comfort. Therefore, architects, landscape architects, and urban designers who research the problem of thermal comfort and landscape analysis in urban parks can use the findings of this article for effective outcomes, especially in parks with climatic conditions use similar in Tehran.

El confort térmico en espacios exteriores es una de las características esenciales de la calidad del medio ambiente urbano; además, puede influir significativamente en el desempeño, el bienestar, el confort y la sensación térmica de las personas. Por ello, en el diseño de los espacios exteriores se deben considerar los índices térmicos de confortabilidad como respuesta a las condiciones climatológicas del entorno en aras de promover su uso frecuente y saludable. El objetivo de esta investigación fue estimar, a partir del enfoque adaptativo, los rangos de confort térmico para espacios públicos exteriores a partir de cada una de las variables físicas del entorno térmico. El estudio se desarrolló en la ciudad de Ensenada durante el periodo cálido. La aplicación de evaluaciones, el diseño del cuestionario y el empleo de instrumentos de medición física, se realizaron a partir de la ANSI/ASHRAE 55, ISO 10551 e ISO 7726. La estimación se realizó con la correlación de las variables físicas registradas y la sensación térmica percibida a partir de dos métodos estadísticos univariables: Medias por Intervalos de Sensación Térmica y Regresión Lineal Simple. Los rangos de confort para la temperatura fueron de 19,2 a 25,1 °C y de 20,1 a 23,8 °C; para la humedad relativa, de 54,3 a 83,6 % y de 0,01 a 99,9 %; y, para la velocidad de viento, de 0,1 a 2,6 m/s y de 0,1 a 5,9 m/s, respectivamente. La estimación obtenida con el primer método de análisis ofreció mayor consistencia respecto a las condiciones reales de evaluación.
