Tropospheric ozone. 4. Photochemical formation of tropospheric ozone: the role of solar radiation.
In the review the factors determining mechanisms of photochemical formation of ozone in troposphere are considered. In the beginning, on the basis of an estimation of the budget of tropospheric ozone the basic from them are allocated. Formation of ozone in background and smogs conditions is separately considered. The description of other photochemical sources is resulted. Formation of ozone is analyzed at lightning categories, an ionic cycle, transport of ozone from a stratosphere in troposphere.
