ABSTRACT:
An ambient air sampler is pivotally mounted to a tether of a balloon-borne sampling device. The air sampler includes an inlet for receiving atmospheric gas samples and a pump for moving samples to one of a number of sample bags. A remotely-controlled valve is used to selectively determine which of the sample bags receives the sample. A pivotal mounting of the air sampler with respect to the tether includes an axle which is stationarily positioned on the tether and bearings which rotatably connect to the axle mounted to a mounting plate onto which the air sampler is secured.
