In the paper, the authors present measurements of turbulence and boundary-layer structure over open winter-time tundra with an emphasis upon the implications of these observations for pollutant dispersion modeling. Vertical profiles of mean wind speed, wind direction and temperature are described, in addition to fluctuations in these quantities. Dispersion coefficients are estimated and compared with the open terrain tracer plume measurements. The work is part of an arctic dispersion modeling program supported by the EPA Cold Climate Research Program. In other aspects of the program, they have investigated plume downwash and dispersion at an arctic industrial site using wind-tunnel model studies and atmospheric tracer field studies.
