Complex Micro-meteorological Effects of Urban Greenery in an Urban Canyon: A Case Study of Prague-Dejvice, Czech Republic
Original language description
This contribution explains and summarizes the latest findings on the positive and negative effects of greenery at the street level. The LES-based PALM modeling system was used for simulations on a previously validated domain. Dense planting of trees can improve thermal comfort by decreasing thermal comfort indices up to 15 °C, surface temperature reduction can even reach several tens of degrees. Air temperature drop is an order of magnitude lower, specifically around 1 °C. Their effect is mostly local, effects in their surroundings were found only in case of air temperature. Dense tree planting close to heavy traffic roads could increase the relative daily-averaged concentration of PM2.5 by more than 30%. The method of planting plays an important role, one row of trees in the middle of the street (+7.5%) has a different effect than two rows on their sides (+18.6%). The hourly averaged maximum concentrations, typically in times of morning and afternoon peak, can increase from 50% to 300%. The increase is dependent on the intensity of traffic or other local emission sources in the planned planting sites, as well as on the quantity, location, and characteristics of the planted greenery.
