Design and analysis of Cross-Appalachian Tracer Experiment (CAPTEX) field trials. Second annual progress report. [CAPTEX]

Technical Report ·
OSTI ID:6303785

Procedures for testing atmospheric transport and dispersion models for distances of several hundred to 1000 km from sources of pollutants are reviewed. The approach is to use both simulated tracer distributions and actual tracer measurements on the US-Canada multi-agency Cross-Appalachian Tracer Experiment CAPTEX '83 surface sampling domain to estimate the accuracy with which the parameters describing the location and distribution of the tracer cloud can be determined from experimental data. In CAPTEX '83, five perfluorocarbon tracer releases were made from Dayton, Ohio, and two releases from Sudbury, Ontario. Surface air samples were collected at 84 locations in northeastern United States and eastern Canada. Three simulation experiments have been conducted with a Gaussian plume model simulating time-integrated surface-layer concentration (i.e., dosage) distributions of tracer clouds from a surface source.
