 Essentially, the larger the tree, the bigger the cooling effect. But not only in terms of shade, right, which I think feels quite common sense, but it's also that larger trees also have the bigger ability to take up more water from its roots. The more water that a tree is able to take up, the more of the evapotranspiration that they're able to provide as well, which is going to give you that direct cooling effect when you're standing beside or standing below a big tree.
