2. Aerosol can scatter, diffuse and absorb part of solar radiation through particles, thus reducing the escape of long-wave radiation on the ground and warming the atmosphere.
3. Smoke over industrial cities and smoke from factories and mines do great harm to human health, as well as acid rain that destroys nature and dust that easily causes explosion, all of which are related to aerosols.
4. The influence of atmospheric aerosol on plants is generally to change the quantity and quality of photosynthetic effective radiation or directly change PAR) to affect the growth and development of plants, that is, aerosol particles in the atmosphere absorb and scatter solar radiation, which reduces the solar radiation received by the ground, leads to the decrease of PAR of plants and hinders the growth of crops.
