Two-photon absorption (ADP) occurs by the action of 2 photons of the UV-A category (λ = 400 nm), each of which has an energy of 3.1 eV, the lowest energy and which reach the ground at 100%.
The energy absorbed is equal to the sum of the energies of the two photons, i.e. 3.1 e.V times 2 = 6.2 e.V
The energy of a single photon doubles at an altitude of 1500 m (2 times 3.1 e.V)
To break the OH bond of water molecules, an energy of e.V. is enough. Water vapor therefore has no chance of rising to condense and form clouds or rain.
The formation of rainwater is a whole different matter.
