I don't know, but there's only one way to find out! Lots of people told me that there was no use at all in measuring air pressure on scales smaller than the US already does with official measurements. But years later, there are multiple papers published and I think IBM now uses their mobile apps to crowdsource barometer data as it improves their weather forecasts. I'm sure there will be naysayers who even say crowdsourcing magnetometer data is useless, but I don't really care or think they're right. AFAIK there isn't a large-scale effort yet to study crowdsourced magnetometer data, so we really just don't know yet. > Are the effects of solar storms that different over small geographic areas? I don't know but now I'm extremely curious how small the measurable variations are in solar storm effects on Earth. And amazingly, there are billions of deployed sensors all around Earth right now that are simply not contributing to a central network. A simple code library is all that's needed to know this answer, which to me, is amazing, and a reason enough to try it out.
