To date, it hasn't been easy to get loads of airborne weather data
beyond major airports. Airliners have had a sophisticated probe system (TAMDAR
Edge) for over a dozen years, but that doesn't help much in those remote areas
where you may only see smaller airplanes or drones. NASA is close to covering
this gap, though: it recently started test-flying a relatively tiny, lightweight
version of TAMDAR Edge aboard an Ikhana drone. The tech promises real-time
weather data on virtually any aircraft, filling in local atmospheric conditions
even in barren places like the Arctic. You could have clearer indications of
when a thunderstorm is brewing in a very specific region, or track previously
unrecorded conditions above hurricanes.
