Caption: Figure 1.
Illustration of cloud polarization. Clouds containing water droplets and horizontally aligned ice crystals scatter thermal radiation from the ground and the atmosphere, directing linearly polarized radiation into the telescope. The two orthogonal linear polarization states are labeled; they correspond to the Q (0°, in orange) and −Q (90°, i.e., horizontal, in blue) Stokes parameter evaluated in the horizontal frame of the telescope. Clouds are depicted as cumulus clouds instead of cirrus for their aesthetic appeal. Objects are not to scale.
