Wing Tip Air Particulate Sampler (APS)

Status

Operated By: 
PI

The APS is a passive sensor designed to gather high altitude dust particles for laboratory research. An APS paddle is deployed from a wingtip pod into stratosphere once the ER-2 has reached cruising altitude, and is retracted before descent. Both wire impactor and oil-film paddles are used. After approximately 40 hours of exposure, the sealed units are returned to the investigator for examination by an electron microscope. The returned particles can be the by-products of meteor decomposition in the upper atmosphere, or the products of massive volcanic eruptions.
