- Abstract
- The ozone layer determines the thermal vertical structure of the stratosphere by absorbing solar UV radiation.
Ozone also has impacts on the global radiative budget. A microwave radiometer is a useful instrumentto monitor the vertical profile of gases in the middle atmosphere. The 110.836 GHz radiation emitted from theatmospheric ozone molecules can be detected at the ground by the microwave radiometer. The ozone spectrumobserved from the ground includes tropospheric effects, especially by variations in water vapor concentration.
These tropospheric effects need to be considered for analysis. In this paper, the water vapor contribution to thespectrum was estimated by comparing two items, bias temperature and intensity, with MPM93 simulated values.
From the method, the ozone profile was retrieved from May through December 2013. The maximum ozoneconcentration of the ozone layer was calculated as 8 ppmv with some seasonal variations. The retrieved profilewas validated by comparing with AURA MLS satellite data, and the deviation was found to be about 10%.
