Redetermination of monochromatic absorption coefficients of methane with regard to thermal conditions in the atmospheres of giant planets. III. Uranus and Neptune
Using the method of deviation of the vertical structure of a planetary atmosphere from the condition of homogeneity, some values of changes of relative concentration of methane with altitude of an atmosphere for models with small and large particles are derived from data of spectrophotometric measurements of the reflecting disks: Uranus - lnγ(p) = -9.111 + 1.119∆ lnp (lnp0 = -0.751, r0≈ 0.063 μ); lnγ (p) = -7.298-2.676∆ lnp for lnp = 1.077 and lnγ (p) = -7.298 + 1.053∆ lnp for lnp ≈ 1.077 (p0 = 1.077, r0 ≈ 0.57 μ); Neptun - lnγ (p) = -8.637 + 1.066∆ lnp (lnp0 = -1.019, r0≈ 0.075 μ); lnγ(p) = -6.357-2.597∆ lnp for lnp ≈ 1.370 and lnγ (p) = -6.357 + 1.314&Delta l;np for lnp ≈ 1.370 (ln p0 = 1.370, r0≈ 0.57 μ) (p - bar). Changes of the values of the monochromatic methane absorption coefficients are also estimated for the spectral region from λλ 380 to 940 nm.
