Atmospheric Refraction

  1. Feb 11, 2007 #1
    Hi,

    I'm working on a project on the Green Flash and have so far been building up a program to produce the 1976 US Standard Atmosphere. I have produced the density profile for the first 86km (which I'll assume to be enough for now) and now need to convert it to a refractivity index profile.

    I'm assuming refractive indices only depend on density changes (since density depends on both temperature and altitude). My question is what mathematical formula should I use? I have been unable to find a formula for converting density profiles into refactive index profiles.

    Thanks,

    Natski

    You probably should look for Ciddor equation. EDIT: here, page 8
