Tipping calibration method for K-band hyperspectral microwave radiometer

  • 摘要: K波段微波高光谱辐射计应用于大气探测方向,能够减少地表至对流层内的大气廓线误差和提高廓线的垂直分辨率.针对平均辐射温度在宽大气频谱和不同天空仰角下存在浮动的问题,结合所统计的北京地区往年廓线数据和晴空条件下的Liebe大气吸收模型(1993),提出了一种微波高光谱下改进的晴空定标方法.相比于传统的晴空定标方法,该方法利用先验的气象数据对定标过程进行优化计算,有利于提高平均辐射温度的预测精度.误差分析结果表明当K波段微波高光谱辐射计采用改进的晴空定标方法时,能够有效减少平均辐射温度对其定标误差的影响.
