Are there some cases where snow-free land and ocean surfaces seem to have similar albedos? if so, where, and what does the land surface most likely consist of in such cases?

Explained

Explanation:

The Ocean surfaces have very low albedo  because they reflect majority of radiations. Similar to ocean surfaces Forests also have low albedo( snow free surfaces)

The forest plants absorb the excess of radiations, ultraviolet rays for their Photosynthesis. And hence, lesser radiations are able to reach to the surface.

Of the different kind of forest cover The coniferous Forest the Albedo Similar to that the oceans 0.08-0.15 % in the summer.

Coniferous in the temperate region 50 degree North to 60 degree north in North America.
