摘要:

文中首先分析了大氣參數(shù)分布的垂直分辨率對(duì)模擬七通道微波溫度探測(cè)器各通道亮溫的影響，通過對(duì)比計(jì)算表明，大氣參數(shù)的垂直分辨率對(duì)微波測(cè)溫通道亮溫計(jì)算的影響為0．2K～0．7K；隨后分析了各通道亮溫測(cè)量誤差對(duì)溫度廓線反演性能的影響，當(dāng)測(cè)量誤差在0．2K～2．0K范圍內(nèi)變化時(shí)，反演結(jié)果的總體均方根誤差為2．1K～3．1K；同時(shí)還分析了單通道缺損、單通道發(fā)生漂移及所有通道發(fā)生漂移等情況對(duì)溫度廓線反演性能的影響。當(dāng)儀器缺損一個(gè)通道時(shí)，對(duì)所缺通道權(quán)重函數(shù)峰值附近高度上的大氣溫度反演有不同程度的影響，對(duì)其他高度上的大氣溫度反演的影響可忽略；單通道漂移0．5K時(shí)，對(duì)反演結(jié)果的影響較??；各通道整體漂移達(dá)到1．0K時(shí)，對(duì)溫度廓線反演有明顯影響；最后，考慮了云霧對(duì)微波測(cè)溫通道亮溫的影響，數(shù)值計(jì)算表明，霧層、濃霾和卷云對(duì)各通道亮溫幾乎沒有影響，層云和積云對(duì)50．50GHz通道亮溫有明顯的影響。

Abstract:

The effect of the vertical resolution of the atmospheric parameter profiles on the simulation of the microwave brightness temperatures is analyzed firstly. The calculation shows that the root mean square differences of the simulated brightness temperatures due to the vertical resolution of the profiles are 0.2~0.7 K. With the numerical experiment used to analyze the effects of the measurement errors of the brightness temperatures of each channel on the retrieval of the atmospheric temperatures, it is shown that the total root mean square retrieval errors are 2.1~3.1 K while the measurement errors of brightness temperatures are 0.2~2.0 K. Furthermore, the effects of the single-channel loss, the single-channel offset and the all-channel offset on retrieving temperature profiles are analyzed. While one channel is lost, there are different effects on the retrieval of the atmospheric temperatures at the levels in the vicinity of the peaks of the weighting functions, and the effects at the other levels can be ignored. While the brightness temperature of any one channel is offset 0.5 K, the effect on the retrieval is slight. While all channels are simultaneously offset up to 1.0 K, the effect is remarkable. Lastly, the results of the numerical calculation indicate that the fog, haze and cirrus cloud have few effects on the brightness temperatures of the microwave channels, while the stratus and cumulus clouds have remarkable effects on the brightness temperatures at 50.50 GHz .
