Dispersion of Tracers in the Atmosphere: Survey of Meteorological Data,
INSTITUTE FOR DEFENSE ANALYSES ARLINGTON VA SCIENCE AND TECHNOLOGY DIV
Pagination or Media Count:
Data on the dispersion of clouds of tracers in the atmosphere, as a function of time after injection, are presented for a variety of altitudes from the planetary boundary layer up to turbopause these data supplement the compilations of Hage 1964 and Hage et al 1966. Within the admittedly wide range of variability of these data, there is no evidence that the behavior for the horizontal dispersion differs between the planetary boundary layer, troposphere, and lower stratosphere. The data show the effective, horizontal eddy diffusivity as being scale-dependent. Results for the lower atmosphere 0-30 km, for the upper atmosphere 80-110 km, and for the ocean near the surface are compared. Modified author abstract
