“…The present result, if it is confirmed by further measurements of the ozone flux into the oceans in different parts of the world, is expected to require an upward revision of published estimates [5,9,7] of the global ozone flux into the earth's surface.…”

“…Similar considerations to those presented above have been given by Fabian & Junge (1970) in connection with their discussion of ozone destruction a t the earth's surface. Their aim was a more limited one, however, and of course no sinks due to rain-out and wash-out were included.…”

A brief discussion of the sink mechanisms of atmospheric pollutants is given and particular emphasis is given to the relative importance of rain-out (wash-out) and dry deposition. The turbulent transfer processes that determine the latter are analyzed in the light of the classical theory for the atmospheric surface boundary layer. The transfer rates t o the free atmosphere (where rain-out and wash-out are the sink mechanisms) and t o the earth's surface (when dry deposition occurs) are computed as dependent on height of emission, roughness of the earth's surfa.ce, deposition velocity (or accommodation efficiency) at the earth's surface and the intensity of the turbulent processes (as dependent on wind velocity). On the basis of such computations the residence time of atmospheric pollutants are computed and the article concludes with a discussion of the relative importance of rain-out (wash-out) and dry deposition in this regard.

“…The computed integrated net production over the globe for the prescribed initial condition and including estimated nighttime destruction (1 x 1012 cm-2 s-') is 5 x 1012cm-2s-'. This is about 100 times theestimated value of theglobal destruction of ozone at the ground (21). The net production rate decreases as the ozone concentration builds up and after 30 days the computed value is reduced to less than 1012 cm-2 s-'.…”

In the stratosphere the relaxation times for transport and ozone photochemistry in a n oxygen-hydrogen-nitrogen system are approximately comparable. Therefore, realistic models used to calculate ozone variations need to be based on the interaction of t h e photochemistry and dynamics in this region.The model used in the present study is the three-dimensional global circulation model developed at the National Center for Atmospheric Research. The photochemical calculations for ozone are carried out as time dependent in a three-dimensional 0-H-N system.The dynamic model is started from an atmosphere initially at rest and then spun up t o a steady state circulation corresponding to mid-January. An initial observed ozone distribution is added and the model is then run through 30 simulated days. Analysis of t h e time variation of the ozone distribution shows that photochemistry dominates the ozone changes in the sub-solar middle stratosphere, and transport processes redistribute t h e ozone poleward and downward into the troposphere. Although the general pattern of ozone changes seem to be correct, the model produces too much ozone in the Southern hemisphere subtropical stratosphere and transports too much ozone into the Northern subtropical troposphere. The conlputed lower boundary flux of about 5 X 10'' cm-' s-' corresponds quite well to estimates given in the literature.Dans la stratosphtre, les temps de relaxation de transport et la photochimie de l'ozone dans un systkme oxygene-hydrogtne-azote sont approximativement comparables.
