The multiple model microwave remote sensor is an important part of the payload carried by Shenzhou 4 spacecraft launched on December 30, 2002 and is also China's first experimental microwave remote sensing system ever operating in space. The system includes three kinds of microwave remote sensors, namely microwave radiometer, radar altimeter and radar scatterometer. The radiometer instrument provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of water and energy cycles. In this paper the authors have described the data processing of the radiometer 1B level product and analyzed the data quality by comparing the data with those obtained by other radiometer sensors. The results show that the microwave radiometer observations of Shenzhou 4 can be used to study the variations of land surface parameters. Although it can be well compared with other satellite passive microwave sensors, the radiometer of Shenzhou 4 has its limitations.
