WebA 100% albedo (highest albedo possible) would be all the solar radiation being reflected away. A 0% albedo would mean none of the solar radiation is reflection and thus all is absorbed into or transmitted through the substance. First we will examine sun angle. WebOverall, Earth reflects about 29% of the incoming solar radiation, and therefore, we say the Earth’s average albedo is 0.29. Snow and ice, airborne particles, and certain gases have high albedos and reflect different amounts of sunlight back into space. csk new replacement

The wavelength of UV radiation (UVR) lies in the range of 100–400 nm, and is further subdivided into UVA (315–400 nm), UVB (280–315 nm), and UVC (100–280 nm). The UV component of terrestrial radiation from the midday sun comprises about 95% UVA and 5% UVB; UVC

WebJun 5, 2024 · Albedo is a measure of how reflective a surface is, how much light energy bounces off and reflects away and how much light energy gets absorbed. (Think hot asphalt on a sunny day. Black asphalt has a low albedo and absorbs light energy, while the brightest white has the highest albedo and reflects the light.) WebDec 19, 2014 · When averaged over the entire Arctic Ocean, the increase in absorbed solar radiation is about 10 Watts per square meter. This is equivalent to an extra 10-watt light bulb shining continuously over every 10.76 square feet of Arctic Ocean for the entire summer. Regionally, the increase is even greater, Loeb noted.

WebSolar irradiance is 1000 W/m 2 at the surface of the moon and the earth. The reflectivity of the moon is about A = 10%. The solid angle of subtended by the moon in the sky is the same as that subtended by the sun ϵ moon = 6.8 × 10 − 5 Sr. I say this because during an eclipse they appear to the same size so it's probably quite a good assumption.

WebSolar radiation is the energy emitted by the Sun, which is sent in all directions through space as electromagnetic waves.
