Tóm tắt

An attempt is made at modelling numerically the effect of atmospheric aerosols on radiation processes. Solar and thermal radiation absorption by aerosol particles is considered and this increases the temperature of the polluted air. On the other hand, thermal irradiation by the aerosols cools the atmospheric layers, containing an increased concentration of aerosol particles and helps to generate altitude temperature inversions. The conclusion is reached that in daytime (particularly under solar radiation) and at night the first and second effects, respectively, predominate. Besides, the effects of atmospheric aerosols on the temperature of the Earth's surface is treated.
