Launching a weather balloon

Every morning at 10AM, one of the WAIS weather observers would launch the daily weather balloon. Stephanie kindly let us watch and help with the launch one day after we finished our field work. The weather balloon tracks temperature, pressure, and humidity at different heights as it travels through the atmosphere.
