Ozone measurement
Ozone is a molecule that contains three atoms of oxygen and thus has the formula O3.The name ozone is derived from a Greek word meaning "to smell". Ozone is a relatively simple molecule, consisting of three oxygen atoms bound together. Yet it has dramatically different effects depending on where ozone resides, it can protect or harm life on Earth. High in the atmosphere about 15 miles (24 km) up ozone acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation. Without this shield, we would be more susceptible to skin cancer, cataracts, and impaired immune systems. Closer to Earth, in the air we breathe, ozone is a harmful pollutant that causes damage to lung tissue and plants. Near Earth's surface, where ozone comes into direct contact with life forms, it primarily displays a destructive side. At ground level, ozone is a health hazard it is a harmful pollutant that causes damage to lung tissue and plants- it is a major constituent of smog.
Ozone layer thickness is expressed in terms of Dobson units, which measure what its physical thickness would be if compressed in the Earth's atmosphere. 1 Dobson Unit (DU) is defined to be 0.01 mm thickness at STP (standard temperature and pressure).The unit is named after G.M.B. Dobson, one of the first scientists to investigate atmospheric ozone (~1920 - 1960). He designed the 'Dobson Spectrometer' - the standard instrument used to measure ozone from the ground.
Ozone layer thickness is measured in Serbia since 23.08.2007. Until now these are the only mesuring of this type in Serbia. Measuring is conducted by the Center for Meteorology and Environmental Predictions (CMEP), Department of Physics, Faculty of Sciences, University of Novi Sad, with the instrument Solar Light Co, Microtops II. The principle of measurement is finding ratio of apsorpcion of UV radiation from sun at three wave lengths: 305 nm, 312 nm and 320 nm. Ozone layer thickness is measured everyday around noon, but only on unclouded bright days.
