Urban areas suffer from higher temperatures due to less vegetation areas and increased heat absorption. This study shows us how vegetation density affects air and surface temperature and humidity at the microclimate scale. The research question of this study How does vegetation density influence on local air temperature, surface temperature, and humidity?
There are three locations that were chosen for the study. Every site shows us a different level of vegetation the first with no plants, the second with a moderate amount of vegetation, and the third with high vegetation. At each site, air and surface temperature, and humidity were measured data were obtained from ground-based field measurements collected following GLOBE protocols. The data included measurements taken at different times of the day to examine changes.The data showed that locations with more vegetation have lower air and surface temperatures, along with higher humidity, but areas with little or no vegetation. This pattern was clearly reflects a vegetation cooling effect at the microclimate level. The study suggests that increasing vegetation density can help reduce local heat and temperature and improve microclimate conditions. This makes vegetation a practical solution for urban heat reduction, especially in school environments, our houses, and neighborhoods.
