Abstract: A spring season sample of isentropic back trajectories for the North Atlantic region is presented. The sample data, derived from select time periods during four spring seasons, are used to investigate the relationship of ...

Abstract: Forecasts of the position and structure of the St. Louis pollutant plume became necessary during the NCAR Fate of Atmospheric Pollutants Study (FAPS). The purpose of the project was to obtain estimates of the mean lifetimes ...

Abstract: We compared observed and model-simulated surface concentration on a spatial wale of 1100 km and a temporal scale of 36 h. The Eulerian tracer model calculated advection by the mean winds and gradient transport for subgrid-scale ...

Abstract: Perfluorocarbon tracer data collected during the Across North America Tracer Experiment (ANATEX) are used to evaluate different meteorological analysis, simulations, and long-range transport calculations. Three basic types ...

Abstract: Perfluorocarbon tracer data collected during the Cross Appalachian Tracer Experiment (CAPTEX '83) are used to determine the accuracy of three trajectory models: an isentropic, an isobaric, and a dimensional sigma model. ...

Abstract: Fourteen observing system simulation experiments (OSSE) wore conducted using the results from a mesoscale model on the Oxidation and Scavenging Characteristics of April Rains(OSCAR) experiment to test the accuracy of ...
