I'm investigating the possibilities of rain or snow on Mars. The
possibility is generally discounted because of the low amounts of

Re - Polarized clouds on Mars, further evidence for liquid water in Solis Lacus, Mars?

I argued below that the polarization seen in clouds on Mars may be
indications of liquid water in such clouds.
It is known that liquid water can cause polarization in clouds on
Earth. This is one of...
