WebThe database of long-term average albedo values is of a set of 12 (monthly averages) +1 (annual average) maps that can be accessed via the Solargis Prospect tool. It provides gap-free albedo data at high resolution and with global coverage. The gap-filled snow-free MODIS product MCD43GF has been used as the primary data source. 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…

Webwhere is the asteroid albedo (precisely, the Bond albedo), its semi-major axis, is the solar luminosity (i.e. total power output 3.827×10 26 W), and the asteroid's radius.
