No as at such a high altitude the atmosphere is composed of a stratified layer of air this region thus gets less heat from the sun and thus less energy is produced to reflect out of this system.
Out of the 51% of units that fall on the earth surface, 23 units get separated and as the 30 % of energy is given off by cloud cover the land surface ice reflects about 6 and the other 50 % is being reflected by the seawater ice.
Oceanic ice absorbs about 0.1 to 0.95 % of the energy that is given the form of short wave sat the outer surface and thus is unable to produce that same amount through the long waves.
