| 摘 要： | 针对武汉MP-3000A型微波辐射计,将无线电探空资料代入辐射传输模式(MWCLD),计算出该辐射计各通道的亮温,再与实际观测的亮温值进行对比,通过个例分析该辐射计观测值与计算值的一致性并判断各通道观测值的合理性.分析结果表明:模式计算值与观测值之间有很好的一致性,并且经过偏差订正或线性订正后的数据,可用于检查辐射计在各个通道的运行状态,从而建立有效的针对地基微波辐射计资料的质量控制方案. |
| 关 键 词： | 质量控制 地基微波辐射计 亮温 |

| Abstract: | In order to obtain the simulated brightness temperatures of each channel based on the MP-3000 in Wuhan, the radiosonde data is introduced into the radiative transfer model. The selected cases are used to make a comparison of brightness temperatures between the calculated values by radiative transfer model and the observational ones by radiometer. Based on analyzing the consistency of these two values, the rationality of the observed of each channel can be judged. The analysis results show that the simulated and observed brightness temperatures have a high consistency, and data from deviation corrections or linear correction can be used to check the working state of microwave radiometer in each channel, so as to establish an effective quality control scheme of the ground-based microwave radiometer data. |
