- qubex 7y agoI suppose that’s true, abstractly speaking. But does it make sense to assume that the world’s meteorological community would put satellites into geosynchronous orbit that are not suited for the purpose of observing the Earth’s atmosphere from geosynchronous orbit? I think we can safely discount that assumption.
- majewsky 7y agoYou're assuming that "observing the Earth's atmosphere" is a yes/no question when it's actually a spectrum. I'm not familiar with the matter, but I can imagine a scenario like "We need to record a very particular part of the EM spectrum and all those existing satellites happen not to have suitable equipment for that."
