Abstract: Based on the ozone concentration of Qinghai Tibet Plateau measured by the the microwave edge detector and ozone detector, the paper analyzes the characteristics of total ozone in each season of Qinghai Tibet Plateau according to the monthly average data of ozone total column concentration obtained from satellite data from 2005 to 2013.The results show that there is a low ozone center over the Qinghai Tibet Plateau in the summer of 2005 to 2013, which is mainly caused by dynamic and chemical reasons.
