[1]在AIRS/AMSU/HSB地球物理反演算法中，采用正演辐射传输模型计算微波亮度温度。微波正演模型的组成部分包括表面发射率模型、表面散射特性对大气下坡反射辐射的影响以及大气透射率模型。在海洋上空，地表模式参数与近地面风速有关。利用Aqua卫星下发射的专用无线电探空仪的大气透射率模型进行计算，结果与HSB测量结果吻合良好。
[1] Within the geophysical retrieval algorithm for AIRS/AMSU/HSB, a forward radiative transfer model is used to calculate microwave brightness temperatures. Components of the microwave forward model include a surface emissivity model, the influence of surface scattering characteristics on reflected downwelling emission from the atmosphere, and an atmospheric transmittance model. Over the ocean, the surface model parameters are shown to be related to near-surface wind speed. Calculations using the atmospheric transmittance model with profiles from dedicated radiosondes launched underneath the Aqua satellite show good agreement with HSB measurements.
