Quality Analysis and Application of Ground-Based Microwave Radiometer Data
2019 International Conference on Meteorology Observations (ICMO), 2019This paper analyzes the detection principle of microwave radiometers and the composition of base data, and introduces a new method to measure data reliability, i.e., to measure the stability of the voltage value based on the lv0 data shear. Through continuous analysis of stability of the Vbb_nd value as well as comparison and analysis of data obtained ...

Ground-Based Detection of Aircraft Icing Conditions Using Microwave Radiometers
IEEE Transactions on Geoscience and Remote Sensing, 1986The potential role of ground-based remote sensors in the detection of atmospheric conditions conducive to aircraft icing is evaluated. Zenith measurements of liquid water and profiles of atmospheric temperature were made by microwave radiometers located at Stapleton International Airport, Denver, Colorado. Radiometer data and sky cover observations for

Design and Development of a Ground-based Microwave Radiometer System
PIERS Online, 2010This paper presents the design and development of a ground-based microwave radiometer system (MWR) for the ofishore oil platform. It will be used to provide long time series of geophysical parameters such as the sea-surface temperature, the near-surface wind speed and the sea ice type.

Assessment of forecast indices over Sriharikota using ground-based microwave radiometer
SPIE Proceedings, 2016Continuous measurements of vertical profiles of thermodynamic variables are important for severe weather nowcasting & forecasting over a region instead of radiosonde observations which are available once or twice daily. Microwave Radiometer (MWR) provides high quality of thermodynamic (temperature, water vapor, and cloud liquid) soundings up to an ...

The analysis of atmospheric absorption model based on ground-based microwave radiometer
2010 International Symposium on Signals, Systems and Electronics, 2010The paper introduces two widely used atmospheric absorption models: MPM by Liebe in 1989 and Ulaby in 1976. Compare between them based on ground-based microwave radiometer, this paper presents an atmospheric absorption model with improvement including local line absorption, noresonant dry air spectrum, water vapor continuum, suspended water droplet ...

New cloud detection method for a stand-alone ground based microwave radiometer
2022<p>Microwave radiometers (MWR) are moving into the focus of national and trans-national meteorological agencies which already operate or which intend to deploy MWR in network setups. The centralized processing of MWR data products within ACTRIS and the imminent integration of MWR into the EUMETNET E-Profile network are two prominent ...

Variability and Dynamic Characteristics of Attenuation Derived by Ground-Based Microwave Radiometer
24th European Microwave Conference, 1994, 1994The dynamical properties of microwave attenuation have been stuied in tenns of fade duration. The attenuation levels due to only atmospheric water vapour, liquid water and oxygen have been estimated by a ground-based radiometer with channels at 20.6, 31.65 and 52.85 GHz at Denver; USA. The measurements period covers about one year.
