Snow
I attempted a grammar cleanup of the section of snow and sea water albedo. I'd appreciate it if someone could take a look at my edits and advise me on how I could further improve the article, or alternatively, if I missed something important with my edit. It seemed to me that the section was a little ad hoc. I tried to make it flow better. I am a failed undergraduate Physics major of several decades, but I still remember my Feynman. -- Alan Canon Alan Canon (talk) 01:22, 15 January 2018 (UTC)

I would like to know more about the reasoning behind the variability in snow albedo. Why is the method of using tarpaulins so expensive, I feel like there could be a bit more explanation regarding this method. However, I find it very interesting that this method can be used and reduces ice melt by so much. Maybe there could be another section dedicated to more information about other countries using this method as well, if there are any. — Preceding unsigned comment added by Envijustice25 (talk • contribs) 16:22, 30 March 2024 (UTC)

"Illumination" Subsection
There are two major errors in this part of the article: "Although the albedo–temperature effect is best known in colder, whiter regions on Earth, the maximum albedo is actually found in the tropics where year-round illumination is greater. The maximum is additionally in the northern hemisphere, varying between three and twelve degrees north.[24]"

The polar regions are, by far, the highest-albedo regions on Earth [1 ] as a result of their snow cover and angle of incidence. The source merely states that the tropical region is a maximum, not that it is the global maximum. Second, as this article's introduction clearly states, albedo is a rate of radiation reflected to radiation received. Thus, the fact that the tropics receive greater year-round illumination is irrelevant. On that note, I don't understand why this section exists at all.

If there isn't any good reason to keep this section, I'd like to delete it. For now, though, I intend to edit that section to correct the two errors I mentioned above. If I've got some sort of conceptual misunderstanding of the subject that makes my edits erroneous, please let me know. Matthew V. Milone (talk) 16:37, 5 July 2018 (UTC)

Unclear sentence in the lead
I've just done some readability improvements to the lead. There is one sentence remaining in the lead that lights up in red with the readability tool, and I have no clue on how to improve it (as I don't fully understand it): While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period.. Can someone improve it please? EMsmile (talk) 13:40, 4 March 2024 (UTC)

What should we add from this article?

 * Thanks for pointing this out. There is probably quite a bit of content that could be woven into this article. And also into climate change mitigation and afforestation? E.g. this sentence in the conclusions jumped at me "It also further underscores the inadvisability of afforestation of native grasslands, which can negatively impact biodiversity". Pinging User:ASRASR and User:InformationToKnowledge. - Is it a disadvantage though that this is a primary source and we are meant to use secondary sources rather? (I am fine with using primary sources for something like this). EMsmile (talk) 10:36, 6 June 2024 (UTC)

Removed image from the lead
I've just removed this image (see on the right) from the lead that had recently been added by a student. The image does not look professional to me, e.g. icebergs don't have that shape, why have those polar bears etc. Also, albedo is not just about ice but also forests. EMsmile (talk) 13:58, 14 June 2024 (UTC)

Better lead image needed?
The current lead image (left) from Greeland might not be ideal because it zooms in on the climate change aspect, rather than explaining albedo in general. Also the caption is perhaps a bit lengthy. EMsmile (talk) 13:58, 14 June 2024 (UTC) EMsmile (talk) 13:58, 14 June 2024 (UTC)
