Irradiance of the surface for each unit frequency or wavelength. The terms spectral flux density or even more confusingly "spectral depth" are also utilised. Non-SI models of spectral irradiance include Jansky = 10 W⋅m⋅Hz and solar flux unit (1SFU = 10 W⋅m⋅Hz). Just as light passing with the environment https://aloisv752oxf0.glifeblog.com/profile
