My department - atmospheric physics. It is located in Scientific-Research Institute for Physics in Petergoph. Studying occurs for most of the areas of physics bat all of these directions can be divided into three main branches.I’ve chosen remote sensing, because it’s for me the most interesting branch. This branch specialized in determination of parameters of atmosphere such as temperature, pressure, concentration of gases and influence of sun radiation through solution of inverse tasks. My department is connected with international high schools and Research centers.My adviser is doctor of physic-mathematic sciences is very clever man. He made a great contribution in science. He helped me to choose a theme of my course work, which I have protected successfully.It’s has been interesting to make wonderful work, which was to write program for determination of optical thickness of atmospheric ozone and comparing results with researches in Southern Europe. Ozone is playing a big role in absorption of ultraviolet radiation of the sun.I’m complete this work. I think that I will be continuing work in this direction.
