Abstract The split of gases in atmosphere under the effect of light is the force of chemical reactions that changes chemical constitution of atmosphere. Concretely, the photo-dissociation of O3 in excited atom O1D (singlet oxygen) is the main source of roots of hydroxyl - main oxidant in atmosphere - that emanates from later reaction of O1D with water vapours in atmosphere. The photo-dissociation of NO2 is the source of individual oxygen O3P (triplet oxygen) that needs for the production of ozone in tropοshare. This work as aim has: The study of levels and the time fluctuation of rhythms of photo-dissociation (JNO2, JO1D) in the region of Eastern Mediterranean, in the station of UOC in Fjnokalia Lasithi with base the measurements that were realised at time period 2001-2004. The investigation of their likely dependence from the optical thickness of atmosphere. The localisation of such dependence shows the interactions between wind and multiplet phase in atmosphere . This work is presented in 5 chapters and is supported, in 7 appendices and bibliographic reports. In capital 1 we study the distribution of radiation, the electromagnetic spectrum, the distribution of radiation in atmosphere, her decrepitude (scattering, absorption) from particles and molecules until reaches in the ground. In capital 2 we study the hovering particles and their effect in the environment and the climate. In capital 3 we study ozone in the troposphere, the photo-dissociation of Ο3 and NO2. Also we study the oxidation of CO, CH4 and others hydrocarbons. In Capital 4 we present the way of measurement of rhythms of photo-dissociation of Ο3 and NO 2, the dependence of quantum yield Φ(λ,Τ) of reaction of photo-dissociation and active cross-section σ(λ,Τ) of a photo-dissociation combination from the wave length, from temperature for Ο3 and for NO2. Finally in capital 5 we processed the measurements of photo-dissociation (JO1D, JNO2) that became in the station of UOC in Finokalia years 2001-2004 and presents the results of measurements in graphs after the required treatment for inference conclusions. The all presentation is supported by 7 appendices.
