2. Belarus Column ozone measurements - a universal ultraviolet solar spectrophotometer-ozonometer • Instrument for measuring of total ozone amount in the atmosphere by means of registration of solar ultraviolet radiation at a number of wavelengths (up to 20) in the spectral region of 295 – 320 nm in dependence of total ozone value, weather conditions, and inclination angle of the Sun. • Possibility of total ozone observations at low sun inclination angles ( 8). • Available measurements of direct sun UV-B spectral distribution in 295 – 320 nm region. PION • Fully automatic processes of measurement and data storage under the control of an external personal computer. • Precise automatic sun tracking system. • Portable construction. • Possible application for treating the variety of other problems of ultraviolet atmospheric optics by reprogramming.

4. Belarus Column ozone measurements - an universal ultraviolet solar spectrophotometer-ozonometer The concept of self-calibration of network ozonometers, announced earlier, gains the further development. PION • a modified procedure of the extraterrestrial constant calibration taking account of changing measured diurnal column ozone data is proposed; • testing and correction of the wavelength setting; • Langley absolute calibration of the spectrometer; • tuning of the sun-tracking system.

8. Belarus UV measurements - an automatic ultraviolet spectroradiometer • Compact instrument for measuring of absolute intensities and spectral distribution of the direct and scattered UV solar radiation in the spectral range of 280 - 450 nm. • Optimized to all kinds of UV radiation measurements (double holographic grating monochromator with dispersion subtraction); possible application for treating the variety of other problems of ultraviolet atmospheric optics by reprogramming. PION-UV • Portable construction.

9. Belarus Information to the public Mapping and UV Index forecast generated specifically for different regions have been realized since 2006. UV Index short-term forecast for all territory of the republic as well as a map (for clear sky and assuming predicted overcast) is submitted to the National news agency BelТА on a daily basis and published in republican newspapers "Zviazda" and "Obozrevatel". These data are also available on the NOMREC site at http://ozone.bsu.by and on the official site of the Republican weather center at http://www.pogoda.by. A corresponding program automatically updating site information has been originated by the NOMREC. Two brochures named “20 years of the Montreal Protocol” and ”UV radiation safe application” were specially published in 2007 for a national meeting of environmental specialists dedicated to the 20th anniversary of the Montreal Protocol.
