Water Vapor

In this profile it can be seen that low clouds contain more water vapor than the middle clouds. Also, in log scale can be seen the presence of a cirrus layer.

Ascent rate

In this case, the balloon quickly ascended (4.9 m/s) because it was filled at 600 bars. Notice the presence of wind bursts before tropopause (16 km).
