WebJan 10, 2024 · The proposed method was performed on monthly and daily albedo prediction both in snow-free and snowy areas. The results showed that the forecast albedo consists of the MODIS albedo data well, with R 2 greater than 0.89 and RMSE less than 0.052 for snow-free areas. Webwhere ρ is the albedo, an adimensional parameter that is defined as the ratio (value 0 and 1) between the reflected solar radiation by the surrounding environment and the incoming solar radiation. As an example, fresh snow has an albedo of 0.75, while an urban environment has an albedo of 0.12, and water bodies—usually around 0.07.
