Photochemical reactions refer to chemical reactions that are initiated or influenced by light. In these reactions, light energy is absorbed by certain molecules, leading to transformations and the formation of new compounds. Full definition
The effects of very short wavelength UV on photochemical reactions in the stratosphere leading to heating at very high altitudes is something that is under appreciated in the climate science community but the meterologists would have likely let them know when to look for these affects.
