A long-range atmospheric tracer field test
Abstract A long-range application of a heavy methane atmospheric tracer system has been carried out using both 12CD4 and 13CD4. The experiment had several objectives including testing a newly developed cyrogenic air sampler, testing a new sample handling apparatus and demonstrating the use of heavy methanes over transport distances up to 2500 km and travel times of more than 100 h. A simple diffusion estimation method applied in conjunction with trajectories produced by NOAA from upper air meteorological data yields good agreement with the tracer data on dosage and arrival time. The duration of observed tracer at the long-range stations was longer than estimated with simple concepts.
