Abstract
Ozone in the stratosphere receives attention as one of the major greenhouse gases. Monitoring stratospheric ozone has been performed by using microwave radiometer. Ozone emits 110.836 GHz radiation spontaneously by 606-615 rotational transition, and it can be detected by a radiometer on the ground. The stratospheric ozone spectrum has been monitored by the microwave radiometer (SORAS) in Seoul. The vertical profiles of ozone from January to June 2011 have been retrieved and the retrieved SORAS profiles are validated by comparing convolved AURA MLS ozone profiles. The retrieved profiles are agreed to AURA MLS data in spring when troposphere is dry. In summer, the profile shows some deviation from AURA MLS data in the high altitude level. It means that the high opacity from the tropospheric water vapor induces the result deviation.
Key Words: Ozone, Vertical profile, Stratosphere, Greenhouse gas, Optimal estimation
