This is why gardeners will put water vapor in the air and water liquid on the ground around their garden on a clear cold night — it protects the local area from cooling as fast because water vapor and liquid both 1) cool much slower than dry air due to their massive heat capacity, and 2) cool even slower because they release their massive latent heat, which means that heat energy is released from them without requiring a drop in temperature — once they're in the latent heat release phase, they just keep shedding energy without dropping in temperature any further.
