Abstract
A partir de mediciones meteorológicas fijas y móviles realizadas en la ciudad de Mendoza se
mostró que los árboles y parques mejoran el confort térmico por efecto de la sombra y la evapotranspiración durante el día; pero al mismo tiempo, las calles arboladas retrasan el enfriamiento nocturno por retención de aire caliente debajo de sus copas. No obstante, el balance
de confort térmico día-noche es favorable. La extensión del efecto de enfriamiento del parque
se extiende hasta unos 800 a 1.000m hacia su entorno, con una disminución de la temperatura
promedio de 1,3oC durante el día y más de 4,0oC por la noche.
Fixed and mobile meteorological measurements performed in the city of Mendoza showed that trees and parks improve thermal comfort by shade and evapotranspiration during the day, but at the same time, trees delays night cooling by retaining hot air under their canopy. However, the balance of day-night thermal comfort is favorable. The cooling effect of parks extends up to 800 to 1000m, to the surroundings reaching an average temperature decrease of 1.3°C during the day and more than 4.0°C at night.
