# Broadband Albedo Conversion Scheme

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!

• Would be beneficial if you could give a little more info. However google got me here: "The effect of a new snow and sea ice albedo scheme on regional climate model simulations" - Morten Køltzow. See paragraph 2.1 . He relates to Collins, but I'm not able to find it in his reference. Aug 5, 2020 at 14:33
• Thank you so much! He indeed mentions it as well.

• Notice that his numbers are different from yours. If I remember correctly it says 0.53 $\alpha_{VIS}$. Aug 5, 2020 at 21:25
• Thank was a typo of mine, thanks for pointing that out as well!
