Introducing meteorological section

The meteorological department, as a part of the space Physics Division for the purpose of meteorological research and the development of aeronautical education activities in the country, was established in 1981 at the Institute of Geophysics, and at the same time, ground-based meteorological activities began. The history of meteorology training in cooperation with the World Meteorological Organization and the Meteorological Organization of Iran dates back to 1357 SH. Also, in order to increase the scientific level of researchers and technicians in the field of teaching and research, Ph.D. level in Meteorology was established since 2004. This section is now one of the most active educational and research departments of the Department of Physics of the Faculty of Geophysics, in University of Tehran .
