| 摘 要： | 基于地基微波辐射计扫频和扫角的通道选取方法,利用青岛气象站2005～2013 年探空数据结合BP神经网络训练数据来反演低层大气参数。将反演得到的低层大气参数与实际探空廓线对比,得到反演的均方根误差小于0.8K。在此基础上,联合辐射计测量参数提出了低层大气参数反演新模式的初步构架,为实时探测低层大气参数提供了更为合理的依据和方法。

| Abstract: | Based on the channel selection method of sweeping frequencies and angles by ground-based radiometers, the low layer atmospheric parameters are retrieved by utilizing the 2005 to 2013 years'sounding data of Qingdao China meteorological station and BP (back-propagation) network inversion method. The inversion low layer atmospheric parameters' RMS error is less than 0.8K compared to the actual sounding data. The principium project of a new inversion low layer atmospheric parameters model is proposed combined with the measured parameters of radiometers, which provides a more reasonable basis and method for the real time detecting of meteorological parameters of low layer atmosphere . |
