Water ice too but slower. There is water in the atmosphere, at least seasonally, that boils off from the poles one at a time. But 100% humidity is not much at all in that thin CO2 atmosphere.

I’ve seen people saying water would sublimate into the atmosphere due to air pressure and temperature but others respond that the relative humidity was near 100%.

Having reconfigured the radar to get consistent data. So it isn’t a hasty conclusion.
