Okay, time to build drones full of atmosphere sensors! The weather forecast is about to get a lot better....this is excellent news for crowdsourcing remote data about the atmosphere. I've been pulling pressure measurements from smartphones for a while, but a core problem is that a lot of weather develops over areas of low smartphone density. Sending out drone fleets will be a most excellent solution; they're reusable…
Unless you're collecting your data under 400 feet, this ruling isn't going to enable such a system. Only "model aircraft" operation is involved.
