Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in … WebThe overall albedo of the Earth - measured to be 0.30 - has a significant effect on the temperature of the Earth, as it changes how much solar energy is reflected by the Earth as opposed to how much is absorbed. …
Albedo is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of radiosity Je to the irradiance Ee (flux pe… WebThe Earth's albedo (or reflectance) is the fraction of shortwave solar radiation that it reflects back to space. It is an essential determinant of the earth's climate, since, in the broadest sense, changes in climate arise …

Due to the contribution of clouds, it's much greater than for the seas. NASA's MODIS instruments on deck the Terra and Aqua satellites, as well as the CERES instrument on the Suomi NPP and JPSS, are used to measure the Earth's surface albedo on a regular basis.
WebAug 30, 2007 · the ground – albedo. The average albedo of our planet is around 0,3: it means that 30 per cent of the sunlight that reaches the Earth is reemitted to the space. The albedo of the Earth surface is nearly dark in the UVB part of the spectrum with values typically between 3 and 5%. So a very small component of the UV radiation is reflected …
