Use of simultaneous radionuclide and other trace constituent measurements to determine fluxes and atmospheric residence timesFinding a way to use atmospheric concentrations to determine source strengths and atmospheric residence times pose considerable difficulties. An approach is to use simultaneously measured radionuclide concentrations as a means of deriving fluxes and residence times for certain atmospheric trace constituents of interest. The study and use of such methods in a pilot field experiment were among the original goals of this program. Four such approaches were studied or developed; suitable sampling and analysis systems were built and tested or are in the final stages of construction; and a small scale field experiment. The evolution is reviewed of the program and the field experiment is described along with the possibilities for its eventual extension to include other species of interest. The four radionuclide based approaches studied are: Mean vertical profiles; Trajectory correlation; Boundary layer discontinuity; and Lead deposition.
