Windsond in Swedish winter

Gränna saw the gathering of hot air balloons during the weekend Andrée Memorial Meet in February 2013. The cloud base was on the low side but turned out quite ok for a nice competition.

A Windsond sounding right before the morning briefing gave us the details of the wind conditions. As an anonymous pilot said afterwards; “I should have trusted the wind sounding more”.

The system has matured a lot lately. The Windsond description is updated with the latest specifications.
