Numerical results for the cloud-free model Earth. Left: total flux F, linearly polarized fluxes Q and U, circularly polarized flux V, and degree of polarization P as functions of α at λ = 350 nm (pink lines), 443 nm (blue), 550 nm (green), 670 nm (red), and 865 nm (brown). The temporal resolution of the thin lines is 15 min. The thick solid lines are the diurnal (24 h) averages. At α = 0°, the time is July 1, 12:00 GMT, 2011. At α = 180°, the time is December 31, 11:45 GMT, 2011. The thick dashed lines are the diurnal averages of a cloud-free “ocean planet” (cf. Fig. 1 of Trees & Stam 2019), thus of a planet without clouds and continents. Right: close-ups of the 15-min time-resolution phase curves for two phase-angle regions as functions of the longitude in the middle of the longitude range that is visible to the observer. The background of each close-up shows the corresponding geographic map of Earth. Note the different vertical scales.
