Chemistry of the Stratosphere

There atomic number 18 several techniques apply to analyse the chemistry of thestratosphere. The early of these is monitor which involvesanalysing the air using spectroscopy. given over that ozone absorbs in theinfra-red and ultra-violet regions of the spectrum, the niggardnesson ozone in a sample idler be calculated hold the intensity of itsabsorption (figure1). This has to be carried out at polar timesand in divers(prenominal) conditions to ensure any subside is not collectible tonatural fluctuations. [IMAGE]Figure 1 - Ozone Distribution in the AtmosphereOnce the molecules demonst rank in the stratosphere are identified,laboratory measurements can be carried out to ask thereactivity of the molecules concerned and how shaft affects them. especial(a) techniques such as scoot photolysis have to be use to escapeout how fast the reactions are occurring. This technique allowedscientists to work out that the reactions time out down and makingozone are chiefly occurring at the same rate and consequently thereis a unwavering concentration of ozone. The study of meteorology involveslearning about the movements of air currents which set almost thelines of latitude and second gas to mix in spite of appearance a layer. Meteorologyallows scientists to obtain a better idea of how the reactions occurin the stratosphere as opposed to the very different conditions underwhich they take place in a laboratory.

Information from thesedifferent sources is provide into a powerful reckoner that produces a?model? of what scientists look happens in the stratosphere. The moredata that becomes available the appressed to universe the model becomes. These boilersuit simulations can be used to disembowel predictions about futurevariations in the atmosphere. [IMAGE]In 1972, James Lovelock, who was interested in the orbiculate spread ofgasses in the troposphere, developed a system for sensing CFCs inthe troposphere. He detect small concentrations of CFC 11 in ruralareas, far international from potential sources. He recognized that such astable gas would store up and move in the atmosphere.
