Recently, we recorded an upper-air launch at our office. Much of the edited video is from a first person perspective, giving unique insight into how our meteorologists launch the weather balloon. It was breezy the day the radiosonde was launched, adding some excitement to the mix.

We normally launch the balloon twice a day. The sounding, as it is called, is released around 4am/pm or 5am/pm depending on whether daylight savings time is in effect or not.

Example output from our most recent sounding:
