摘要
利用3个辐射传输模式对无冰无降水情况下的星载微波辐射计亮温测量进行仿真研究,通过模拟计算结果与同步卫星数据之间的比较分析,确定了用于反演算法研究的前向模式;利用该模式,提出了基于物理的星载微波辐射计海洋大气参数(包括海面风速、海表温度、大气垂直积分水汽量以及积分液态水量)多重线性回归算法。
Based on the microwave radiative transfer theory, three radiative transfer models are used to simulate the brightness temperature measured by a satellite microwave radiometer under conditions of no precipitation or ice. A forward model for the development of the retrieval algorithm is established through comparison of the simulated results with the simultaneous satellite measurements. Based on the simulation by the selected forward model, a multiple linear regression algorithm is presented for the retrieval of oceanic and atmospheric parameters including sea surface temperature, surface wind speed, integrated water vapor and integrated cloud liquid water from satellite microwave radiometer microwave.
