| 摘 要： | 利用武汉站高时空分辨力探空资料(3h,30m)与同址的MP-3000A型地基微波辐射计资料,分析了微波辐射计探测偏差的日变化及时间序列变化特征。结果表明,微波辐射计对大气要素的探测具有较高的探测准确度,但仍然存在一定的探测偏差。温度的探测偏差大值区出现在午后,相对湿度及水汽密度的探测偏差大值区则在凌晨;温度及相对湿度探测误差的时间序列表现为起伏较大,而水汽密度则相对平稳,降水,特别是强降水,会对微波辐射计的探测准确度产生较明显的影响。 |

| Abstract: | The diurnal variation characteristics of microwave radiometer measurement deviation and the time series are analyzed by using the high temporal spatial resolution radiosonde data (3 h, 30 m in vertical) and the corresponding MP 3000A microwave radiometer data of Wuhan. The results show that the measurements of atmospheric elements have higher accuracy, but there are still some deviations. The large values of temperature deviation are found in afternoon, and those of relative humidity and water vapor density are in the early morning. The detection deviations of temperature and relative humidity time series exhibit noticeable variations, and water vapor density is relatively stable. The precipitation, especially heavy rain, has significant impact on the accuracy of microwave radiometer detection. |
