Microwave remote sensing of stratospheric trace gases using digital Fast Fourier Transform spectrometers

摘要

The Institute of Applied Physics observes middleudatmospheric trace gases, such as ozone and water vapour,udby microwave radiometry. We report on the comparison ofudmeasurements using a novel digital Fast Fourier Transform andudaccousto optical spectrometers. First tests made on ground areudpresented as well as first experience about the use of suchudspectrometers under aircraft conditions.
