Rj. Lagomarsino et N. Latner, A TETHERED BALLOON AIR SAMPLING SYSTEM FOR DETERMINING THE VERTICAL-DISTRIBUTION OF ATMOSPHERIC TRACERS, Journal of the Air & Waste Management Association [1995], 47(9), 1997, pp. 990-994
A lightweight, constant-flow air sampling pump has been adapted for at
taching to a balloon tether line for the vertical sampling of atmosphe
ric perfluorocarbon tracers. Constant flow was maintained up to an alt
itude of 6,250 m. The pump design, construction, and sampling techniqu
e are described. Typical vertical concentration results obtained durin
g a perfluorocarbon tracer release experiment are presented.
