762nm氧分子吸收带的大气透过率模型用包含温度和气压的多项式表示,其多项式系数表示为入射角的余弦的另一个幂级数.类似地,还给出了平均大气透过率模型.数值试验表明,在绝大多数情况下,透过率模型与平均透过率模型的拟合误差(RMS)分别小于0.0001和0.0005,其极大误差分别小于0.0005和0.003.此二模型已用于从空间探测气压廓线的研究.此外,还给出了大气透过率间隔误差的订正方法.

An atmospheric transmittance model for molecular oxygen absorption band near 762 nm is expressed by a polynomial including temperature and pressure.The polynomial coefficients are expressed as another power series of cosine of incident angle.Similarly,a mean atmospheric transmittance model is also given.Numerical tests indicate that under vast majority of circumstances the fitting errors ( RMS ) of the atmospheric transmittance model and those of the mean atmospheric transmittance model are less than 0.0001 and 0.0005,and their maximal errors are less than 0.0005 and 0.003,respectively.Both models were applied to the study on remote sounding of atmospheric pressure profile from space.In addition,a correction method is given for the interval error of atmospheric transmittance.
