Study of Atmospheric Ozone Variations from Surface and Satellite Data: Comparative study for the total amount of ozone over Egyp,Used
Delivery time: 8-12 business days (International)
As it is more or less agreed that atmospheric ozone is created by the action of sunlight on Oxygen, it might reasonably by expected that the Ozone amount would be at maximum in Summer and at a minimum in Winter. Observations show that this is not the case, But theories suggest a maximum Ozone in quantity in Summer (June) and a minimum in Winter (December) in Nhemisphere whilst in reality the maximum in high Nlatitudes is about March and the minimum about October. The discrepancy between theory and observation is most probably due to meteorological processes. One of the most important minor constituents of air is triatomic Oxygen (O3). Ozone has been existed in the atmosphere. Results had demonstrated and suggested that the absence of the part of the suns spectra in the UltraViolet band be due to absorption by atmospheric Ozone. There are many kinds of measurements and observations of the total amount of Ozone. The measurements come from the groundbased instruments (DOBSON and BREWER Spectrometer) during scientific missions and TOMS (Total Ozone Mapping Spectrometer) Satellite.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
