Vegetation affects urban mesoclimate and microclimate by intercepting solar radiation, directing air movement, and affecting air temperature. Microclimate, mesoclimate and macroclimate can be used to describe the climate of a given location. Macroclimate covers hundreds of square miles and parameters such as precipitation levels, temperatures and winds. Mesoclimate covers areas of tens of square miles and describes how conditions vary from the prevailing macroclimate due to the effects of water bodies, topographic features (terrain), and other landscape influences. A microclimate …

Are the benefits that trees afford our communities greater than their costs? The answer is yes. A study of future benefits and costs of a tree planting program in Chicago found that the projected value of trees, when measured by such things as increased property values and decreased energy use, is nearly three times greater than the …
