Abstract:

The contribution of weak water vapor lines, which are usually neglected in estimates of solar radiation attenuation in the atmosphere, to the total atmospheric absorption in the near infrared and visible regions is studied. Calculations are based on the HITRAN–96 and “global” ab initio results [H. Partridge and D. Schwenke, J. Chem. Phys. 106, 4618–4639 (1997)]. It is found that the additional absorption amounts to 2–4% of the overall water vapor absorption for horizontal paths of different length, and it is most significant in the visible spectral region.
