Relative Humidity & Temperature

As in previous launch, the sky was whole covered by a middle altitude cloud layer (stratonimbus) between 7 and 8 km. It can be seen in RH profile.

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).
