Atmospheric remote sensing using multi-channel ground-based microwave radiometer

This paper proposes a self-developed multi-channel ground-based microwave radiometer that uses a brightness temperature and data inversion method. We compared the radiometer data and the radiosonde observations, and then analyzed the radiometer observations in terms of brightness temperature, inversion temperature, and water vapor profile accuracy. Results show that the microwave radiometer has a small observation error of brightness temperature and the neural network inversion profiles of atmospheric temperature, water vapor, and other parameters are accurate and reliable. The proposed radiometer has practical applications.
