An experiment is described in which a trajectory forecast model was used in real-time to estimate the transport of debris associated with a large chemical explosion in the south-western U.S. The forecast trajectories were used to vector sampling airc

Dust lofted by a large explosion was tagged with an elemental tracer and sampled by aircraft at times between 42 min and 24.5 h following the detonation. The tracer adhered to the finer particles of dust, and provided a sensitive technique for measur

Data collected as a part of this study from 1968–2002 and data from other studies from 1950–1967 show that themaximum atmospheric concentration of tritium gas (HT) occurred in the early to mid 1970s, which corresponds to theera of frequent, large

Although the Antarctic circulation cell is a statistical construct, its ability to transport trace gases and aerosols to the continent has been discerned experimentally by the use of deuterated methane atmospheric tracers. Atmospheric tracer experime

A series of sampling flights was made to determine the vertical distribution of HT and HTO in the upper troposphere and lower stratosphere up to 18-km altitude. The HT appears to be well mixed, but striking vertical gradients of HTO were found in the

Two sampling flights were made to determine the latitudinal distribution of tritium gas in the troposphere between California and Antarctica. These data, confirmed by shipborne and land station samples, were used to parameterize the interhemispheric

The deuterated methanes, 13CD4 and 12CD4, are useful as tracers for long-range (>500 km) atmospheric transport. They are easily synthesized and released. Sampling is accomplished by collecting about 330 l of air and chromatographically separating the

A cryogenic whole air sampler and a filter sampler were used, simultaneously, on a balloon platform to capture and preserve all significant stratospheric chlorine species with the exception of Cl and ClO at altitudes of 15, 20, 25, and 30 km. The who

Measurements of the isotopic composition of methane in the Antarctic atmosphere have indicated the presence of either /sup 12/CD/sub 4/ or /sup 12/CHD/sub 3/. The concentration is about 1.3/times/10/sup /minus/16/(v/v). This concentration is at least
