Vertical decisions
Atmospheric opportunity
Fleet-observed GPS ground speed by altitude band. Longer bars indicate faster air sampled by the balloons.

Fleet comparison
Average flight level versus average GPS ground speed. Bubble size shows distance from launch.
Time × altitude strategy
GPS speeds sampled near the selected balloon, grouped by time and altitude. Team tracks show the layers they actually chose.
