| Research Abstract |
Water vapor plays an important role in stratospheric chemistry as a source of HOx molecules that cause catalytic ozone destruction, and is also major greenhouse gas that affects the radiative energy balance in the middle atmosphere. In order to obtain the vertical profiles of stratospheric water vapor, we have newly developed a 22GHz microwave spectroscopic radiometer equipped with room temperature HEMT amplifiers and a digital FFT spectrometer. The radiometer shows good receiver performance without any cooling system, and the portability of the instrument is drastically improved compared with cooled radiometer systems. The radiometer allows us to observe the stratospheric water vapor through day and night from ground at sea level.
