| 摘 要： | 为了充分了解微波被动遥感大气温度廓线的能力,为星载微波辐射计研制及今后的资料解释提供必要的技术基础,开展了采用50～60 GHz氧气吸收带内的7个通道反演大气温度廓线的数值模拟研究.利用微波辐射传输模型模拟了微波辐射计各通道亮度温度,在此基础上建立了大气温度廓线的统计反演方案.统计反演的数值试验表明,50～60 GHz微波通道对大气温度廓线有一定的遥感反演能力.

| Abstract: | In order to understand the capability of retrieving temperature profiles from satellite-borne microwave radiometer data and provide the necessary technical basis for the development of the satelliteborne microwave radiometer, a numerical simulation study was conducted using 7 channels in the 50-to 60- GHz oxygen absorption band. A microwave propagation model was used to simulate radiometer brightness temperatures. Then a statistical scheme was developed to retrieve atmospheric temperature profiles. Numerical experiments with the statistical retrieval method show that microwave sound can provide the useful information on temperature profiles. |
