It's NOT an Oblate spheroid? That's what I always thought!Yes, of course. This fact was apparently known to even the Ancient Egyptians. The length of degree varies as a function of Latitude. There exists a regular additive series which expresses this change.
We can talk about Egyptian Cubits, if you like, or even the ancient measure of Stadium, which is apparently 185 meters or 1/10 minute of arc.Modern 'shape of Earth' stuff revolves around whose 'spheroid' you use as reference.
When I talk about the shape of the Ionosphere, it is NOT conformal to the shape of the Earth, but rather responds to the Solar Wind, as well. At a particular point on Earth, the Schumann Resonance measure will change as a function of time of day and solar orientation.
Too much is never enough
