UP IR turns it off because non thermally activated GHG
molecules near the surface that absorb UP photons can't absorb DOWN photons.
The end result is there's virtually no heating beyond the first few micrometers and
the molecules near the surface just keep picking up more and more energy as latent heat until they have enough energy to vaporize and then they leave the surface and quickly convect upwards because water vapor is lighter than air.

the molecules near the surface just keep picking up more and more energy as latent heat until they have enough energy to vaporize and then they leave the surface and quickly convect upwards because water vapor is lighter than air.
These photons in these ranges will be immediately be absorbed by the respective O2 or N2
molecules near the surface, that is a swag but a sure one.
