Lunchtime Photo

This is Catalina Island, shot during takeoff from John Wayne Airport. The picture was taken around noon, so I don't know why the sky is reddish at the horizon.

      I thought it was “Red sky at morn, sailors take warn; red sky at night, sailors delight; red sky at noon, drunk too soon”.

    Best guess (and a really rough one): Red clouds, not red sky, and looking the the nearer ones, clouds with a lot of water droplets. That suggests Mie scattering in effect, but Mie scattering does not have a strong wavelength dependence. They're all scattered about the same.

    But you're also looking at clouds close to the horizon, hence passing through a lot of atmosphere to get to you. Maybe that introduces enough Rayleigh scattering to make it tilt toward the red.

    But I am very much ready to be proven wrong here.
