The albedo value of a surface affects what?
Consider the reflectivity of surfaces.
Given the following data: Incoming solar radiation (Rs) = 20 MJ/m²/day, Albedo (α) = 0.2, Outgoing longwave radiation (Rnl) = 6 MJ/m²/day. Calculate the net radiation (Rn).
Use the formula discussed and plug in the values correctly.
If a region has an average temperature of 25°C and a wind speed of 3 m/s, discuss how these factors would influence the accuracy of the Penman Method in that region.
Consider all factors from the equation and how they interrelate.
