Short-wave radiation system: dire(cid:272)t (cid:271)ea(cid:373) radiatio(cid:374)-the radiation from the solar disc itself, the solar radiation that comes from a local star. Not all of our light is direst beam radiation. This is the beginning of the whole process: diffuse radiatio(cid:374)- what comes from the rest of the sky. Even when you do(cid:374)"t look at the sun there is still radiation. Some of it goes right down through the atmosphere and gets all the way some, some almost a quarter gets absorbed (gets heated up by) by the atmosphere. The blue wave lengths are shorter and they get scattered which is why the sky is blue, dominantly the blue wavelengths as to why the sky is blue. Another type of diffuse radiation is scatter through atmosphere or the ones passing through the clouds.
