Microwave 110/115 GHz radiometer for simultaneous atmospheric ozone and carbon monoxide measurements
Journal article, 2025
We present a microwave radiometer developed for long-term monitoring of the northeast China upper stratosphere and mesosphere. The characteristics and observation methods of the radiometer are introduced. The ground-based microwave radiometer with a compact optical system is designed to allow simultaneous monitoring of O3 and CO lines thermal radiation, with noise temperatures of 690 K (O3) and 940 K (CO). A new baseline correction method is applied to obtain the baseline for the O3 radiometer channel, which solves the problem of different channel gain caused by the frequency-switching technique. The retrieval procedure is also described, which includes the tropospheric attenuation compensation at both frequencies. The estimated vertical confidence interval of O3 and CO inversion are about 25–60 km and 65–95 km, respectively. The ARTSGUI software is developed to optimize the microwave radiometer data retrieval and visualize the process of measurement calibration and O3/CO data inversion.
