WebApr 11, 2024 · Measuring earth’s albedo is a challenge. The level of reflectivity is subject to daily and seasonal changes and depends on the level of snow, ice and cloud cover. Clouds reflect about 50% of light from the sun, while snow and ice reflect more, compared to just 10% reflectivity from oceans. WebCloud albedo is a measure of the albedo or reflectivity of a cloud. Clouds regulate the amount of solar radiation absorbed by a planet and its solar surface irradiance. Generally, increased cloud cover correlates to a higher albedo and a lower absorption of solar energy. earth wire hs code
