Visualization and Prediction of the Albedo Map on the Algeria Ground, according to Coordinates of Latitude and Longitude

Abstract

Aims investigation study to predict the albedo number as a function of latitude and longitude coordinates of the Algeria area, which is situated in North Africa. The estimated range of latitude is between 18.5° and 37.7° whereas the longitude is between –8.5° and 10.5°. The study takes the database as the real data, which is considered comparable values as a reference of the confirmation. An ideal reflector is going to have an albedo of 1, whereas an object that has an albedo of 0 is going to absorb any radiation that strikes it. Albedo is a measure of how much solar radiation, or sunlight, a surface reflects. It can be stated as a percentage or a decimal number, where 0 represents complete absorption of all incoming light and 1 represents a perfect reflector. The prediction model is divided into two parts the first part gives two formulas g₁ and g₂ which depend on the longitude and latitude of the coordinates of the area, respectively, and then added together g₁, and g₂, and divided by 2 to take the albedo number. for the second part do the correction between the model and experimental data, which gives us some errors, in this case, create a new correlation of the errors estimate f₁, and f₂ and add in the old correlation. Finally, a new correlation is corrected and the results give a perfect approximation of the best way.
