Anthropogenic atmospheric pollution changes the amount of solar radiation penetrating through the atmosphere. Such effect is called global dimming and is associated with changes of spectral and geometric composition of the incident solar radiation. We found substantially higher CO2 net ecosystem exchange (NEE) in spruce stands during cloudy sky conditions (characterized by high amount of diffuse radiation) compared with clear sky conditions. The main reasons of this phenomenon will be discussed.
