Our family is planning to go to Australia later this year. Naturally, I decided to browse the Internet to learn more about this country and the adventures it offers. It turned out that Australia is a beautiful place with a huge variety of exciting outdoor activities. I also learned that Australia, unfortunately, has the highest rate of skin cancer (1:30) in the world (http://www.healthinsite.gov.au/topics/Cancer_Statistics). This fact made me think about the ozone depletion and the related threat to people in different countries.
Atmospheric ozone plays a vital role in protecting the life on Earth from harmful solar ultraviolet radiation. Since 90% of all ozone is located in the stratosphere (from 8-12 to 48-50 km), stratospheric ozone receives constant attention from many scientific, industrial and government organizations. Canadian government, for example, supports the maintenance of WOUDC database (World Ozone and Ultraviolet Radiation Data Center, http://www.msc-smc.ec.gc.ca/woudc). WOUDC collects and systematically stores all ozone measurements from different instruments worldwide, and anyone can use these data for free.
That is why continuous measurements of stratospheric ozone, development of new, more accurate, measurement methods, and use of the newest and more accurate data for ozone studies is extremely important.
