Water Vapor

The mixing ratio profile shows the same cloud layers than RH profile. It is interesting to remark that cirrostratus layer is divided in two sublayers.

Ascent rate

In this case there were not many wind bursts to increase quickly the radiosonde ascent rate (its average was 4.7m/s).

Photo gallery

Taken from the launching point. Some pictures show the direction towards they were taken. 
Observe that the cirrostratus layer produces a halo around the Sun. Also, observe the water bottle used as the weight of the balloon to obtain a correct ascent rate. This weight weighs 1100 grams.
