How much of the sun's radiation is reflected
WebThis balance is called Earth's energy (or radiation) budget. Most energy received from the Sun is in the visible (or shortwave) part of the electromagnetic spectrum. About 30% of the incoming solar energy is reflected. It is reflected back to space by clouds and aerosols or bright surfaces. The ratio of reflected-to-incoming energy is called ... 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. Webincidence typically reflecting more light than high angles of incidence. Radiation can reflect off a surface more or less equally in all directions at once or in only one direction as light …
WebOn a perfectly clear or cloudless day, when the Sun is directly overhead (or at the "zenith"), solar irradiation is still reduced due to absorption (16%) and reflection (6%) by particles in Earth's atmosphere. These particles include … WebThe reason for the seasons lies in the amount of the Sun's radiation that reaches the Earth. The amount of energy put out by the Sun is a constant. ... Clouds reflect 20 percent, and the remaining 4 percent is reflected by the surface. The energy that was absorbed can be reradiated. Of the reradiated energy, 70 percent is lost to outer space ...
