大气辐射传输模型的比较研究

 讨论了三种通用的大气辐射传输模型的特点和使用限制，用辐射传输定律作了数值检验，并与实验测量资料作了比较。结果表明，氧碘激光和氟化氢泛频20P4激光谱线大气透过率的计算值与实验测量值吻合，氟化氢泛频20P5却出现严重偏差。还研究了大气气溶胶种类对大气透过率计算和测量的严重影响。

Inter-comparison of models for radiative transfer in the atmosphere

The characteristics and limits of the general three models of radiative transfer in the atmosphere are discussed. Numerical tests were carried out by means of both the radiative transfer's law and the transmittances measurements in the real atmosphere. The results show that there are very good agreements between the transmittance measured in the fields and calculated by the model for COIL and HF overtone 20P4 lines, but big error for HF overtone 20P5. Moreover, the significant influence of aerosol types on transmittance of the laser beam through the atmosphere is studied.
