Isolated sphere capacitance is 114 pf/meter radius.  Earth is roughly 6750
km radius, so 6.75E6*114E-12 = 769E-6 F, awfully close to the quoted 800 uF.

Of course, you can also consider the gap between the surface of the earth
and the somewhat conductive ionosphere as a cavity resonator, which like all
cavities, has several modes (transverse, longitudinal, etc.)

You'd also need to consider that it's a pretty leaky capacitor.
