Light intensity (red), moss temperature (blue) and air temperature (green), December 14-24.

This data shows that, late each day, the temperature of the mosses falls rapidly as the light intensity (PPFD) declines, but stops once the mosses reach freezing point. The plants stay at that temperature all ‘night’ until the sun rises higher in the sky next morning.
