Ds HOLZMAN: against doing this fron an understanding of turbulenes and things of this sort. What I am interested in finding out is what the distribution of thie stuff is with altitude and hov long it stays there. You might be eble to have sous minimal program of ballon activity measurenante vhics might give you this. this sort. Distribute them around the sarth or something of You could get a balloon program, on a very mall scale which would give you sous idea but the foeus of the problem would be to determine how mich is up there and vhat ite distribution is end what its loss fros the atmosphere would be. KELLOGG: Did I understand you to mean in a little different way, and it is also I think vnet Marry meant, that we won't be able to use this data for any fancy analyste of diffusion rates but it will be some direet evidence on where the saterial goes which we do not at present havet WEXLER: And if you can just throw additional light as to whether the vertical movenent of the stepdown is done mostly be rain or by nonrain. That nonrain is extremely important because if this is etratespheric stuff, it has got to get down from the stratosphere to rain-bearing levels so that you have to throw light on beth of those uechentsas. LIBBY: Would you gentlemen hasard « guess as to the diffusion ecefficients? WEXLER: X lambasted those things yesterday and theafaore I have disalloved nyself. I just don't delieve a mmber can really express the complexity of this whole problem. Comprising a whole range of scuething that effects cigarette snoke to thunderstorm. ‘hey all enter into this business but I do think that we have plenty of evidence, indirect evidence, that om DOE ARCHIVES
