I had this albedo conversion written down: $$\alpha = 0.53\alpha_{VIS}+0.47\alpha_{NIR}$$ I had on my notes that this equation was form Collins et al (2002). However, I cannot find where this came from at all. Hope you guys can help me out!
• Notice that his numbers are different from yours. If I remember correctly it says 0.53 $\alpha_{VIS}$. – J. Fregin Aug 5 at 21:25
