From Salt Lake City. . .>I was wondering what that giant blue ball was hanging outside my front window. . .

i just hope your umbrella is in good working order.. looks like you're going to be needing it!

But On the bright side, at least now it's easier to get to the TItanic.

Fascinating. Nice find.

I would like to see the ball subdivided into fresh water and salt water. I think that would have more visual impact with reference to the limited resources on the planet.

via the link..
here are a couple of graphs showing distribution..

All the water and all the air. I'm not sure whether the air is represented as-is, ie a sliding scale of density, or whether it's all been compressed to 1 atmosphere. Either way, it weighs 5140 trillion tons.

The average mass of the atmosphere is about 5 quadrillion (5×1015) tonnes or 1/1,200,000 the mass of Earth. According to the American National Center for Atmospheric Research, "The total mean mass of the atmosphere is 5.1480×1018 kg with an annual range due to water vapor of 1.2 or 1.5×1015 kg depending on whether surface pressure or water vapor data are used; somewhat smaller than the previous estimate. The mean mass of water vapor is estimated as 1.27×1016 kg and the dry air mass as 5.1352 ±0.0003×1018 kg."
