Spectrally resolved actinic flux and photolysis frequencies of key species within an indoor environment

Ultraviolet and visible (UV-VIS) radiation is responsible for the photolysis of stable trace gases and production of highly reactive atoms and radicals in the lower boundary layer of the atmosphere. Photolysis frequencies of the key species in the atmosphere depend on the spectrally resolved actinic flux. However, to date direct measurements and modeling of the actinic flux and photolysis frequencies of species relevant for indoor atmospheres are scarce.
