Uncertainties in the measurement of the atmospheric velocity due to balloon-gondola pendulum-like motions

Balloons lead to the highest vertical resolution of air velocity data actually attainable from atmospheric soundings. However, the pendulum-like motion of the balloon-gondola system may significantly affect these measurements if the distance between balloon and gondola is large. This may prevent the...
