We launched a weather balloon where one of the sensors was an accelerometer. The data from it show all parts of the flight (1 launch (0 m), 3 bursts of the balloon (35,800 m), 4 landing (0 M)).
We also measured the temperature, which shows that the balloon left the tropopause and entered the stratosphere at 9:20 a.m. at an altitude of 18 km (3). What is interesting is that the data from the accelerometer shows that at that moment the balloon experienced a relatively large shock and subsequently stopped flapping as much as it did in the troposphere. What is it caused by?
The Z axis was pointing up in the direction of flight.
The balloon was launched on 17.9. 2021 from the Czech Republic.
- The end of the tropopause and the beginning of the stratosphere
- Balloon burst
Update: In flight photo
There is a balloon at the top, a parachute in the middle and a small round probe at the bottom. When the balloon burst, everything fell together in a big mess.
