Every 12 hours, the National Oceanic and Atmospheric Administration (NOAA) launches weather balloons from approximately 70 locations across the US. While these do provide valuable data, a lot can change between those intervals and those locations. That's why a new project is taking advantage of something that's already going up in the sky on a much more frequent basis and in a higher number of locations – Southwest Airlines jets.
