D Dispersion Models
Fig. D.3 Approximate
timescales for vertical mixing
of gases into different layers
of the atmosphere (vertical
arrows). The vertical bars
show the variability in the
height of the boundary layer
and the tropopause. Based on
estimated values by Jacob
(1999)
Fig. D.4 Approximate timescales for horizontal transport of gases in the troposphere. Based on
estimated values by Jacob (1999)
