If all the radiation from space reached Earth we would all die in a matter of minuets
about 5% of radiation is lost before reaching Earth's surface
More radiation reaching the Earth's surface.
90% of radiation reaching the surface of the earth is absorbed! and 10% is reflected into space.
The uv index
ozone
visible light
Ultraviolet waves
It blocks (some of) it from reaching the surface of the Earth.
It blocks Solar ultra-violet radiation from reaching Earth's surface.
Cloud cover blocks incoming solar radiation from reaching the earth's surface
ground radiation
25% is absorbed by clouds.25% is reflected by clouds.So 50% of the sun's radiation is lost before it reaches earth's surface.See the diagram link below.
