<p>I had this albedo conversion written down:
<span class="math-container">$$\alpha = 0.53\alpha_{VIS}+0.47\alpha_{NIR}$$</span>
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!</p>

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.

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 $\alpha_{VIS}$.

Thank was a typo of mine, thanks for pointing that out as well!

(Asked by: username_0 on 2020-08-05)

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!
