| Abstract |
Monitoring the variation of the atmosphere has been performed by using several spectroscopic techniques from ultraviolet to radio-wave. The gas molecules having permanent dipole moments emits the microwaves at specific frequencies. During the propagation, its intensity and line shape is changed by the collisions with other atmospheric gases known as the collisional broadening. If we measure the atmospheric microwave spectrum, it results from the sum of the spectra emitted at each vertical layer, so we can retrieve the atmospheric profile. The profiles of stratospheric ozone and water vapor over the Seoul have been measured by the microwave radiometer of 110 GHz and 22 GHz. In this study, we will demonstrate the measured atmospheric microwave spectra and its spectral shape variation due to the meteorological condition. The vertical profiles of ozone and water vapor over the stratosphere are also shown in this study. This technique is important to study the climate change as it gives information of the upper atmosphere. Although it is known as the upper atmosphere is stable, but it means that it takes long time if its status has been changed.
