Description of the payload
An hygrometer is an instrument which measures the water vapor content in the atmosphere. This one was launched in support of the MAGIC (Mesospheric Aerosol - Genesis, Interaction and Composition) rocket, launched a few hours later and wich aim was to collect the meteoric material in the atmosphere and to return it to the ground. After the flight everything was taken to laboratories where various methods will be applied to analyze the collected "stardust".
In this frame work the balloon-borne hygrometer was launched some hours before the rocket to provide detailed measurements of water vapour as it serves as an excellent tracer for mesospheric transport.
These measurements have been done using MISU's optical hygrometer technique.
