Abstract

A detailed radiative transfer calculation has been carried out to estimate the effects of rotational Raman scattering (RRS) on satellite measurements of backscattered ultraviolet radiation. Raman-scattered light is shifted in frequency from the incident light, which causes filling in of solar Fraunhofer lines in the observed backscattered spectrum (also known as the Ring effect). The magnitude of the rotational Raman scattering filling in is a function of wavelength, solar zenith angle, surface reflectance, surface pressure, and instrument spectral resolution. The filling in predicted by our model is found to be in agreement with observations from the Shuttle Solar Backscatter Ultraviolet Radiometer and the Nimbus-7 Solar Backscatter Ultraviolet Radiometer.

摘要

已经进行了详细的辐射传输计算，以估计旋转拉曼散射（RRS）对卫星后向散射紫外辐射测量的影响。拉曼散射光的频率相对于入射光发生了偏移，这会导致在观测到的后向散射光谱中填充太阳夫琅禾费线（也称为林效应）。旋转拉曼散射填充的大小是波长、太阳天顶角、地表反射率、地表压力和仪器光谱分辨率的函数。我们模型预测的填充情况与航天飞机太阳后向散射紫外辐射计和雨云7号太阳后向散射紫外辐射计的观测结果一致。
