VOICE: The Signal Cerpe has been trying to measure width by setiing up smoke trails from reckets, and hes been unsueceseful because the diffusion rate is so great that they den't even have a chance to photegraph it. Thia is the heriszontal? Yow this ig just disatpation of the vaper trail itself, with the *"OXICKs smoke trail, KELLOGG: I've heard this too. RB, PLESSET: It just breaks spart. VOICE: De you think this in the region below 100,000 feet; or is this up in the very high region above the ozone layer? VOICEs TI don't think it went up that high. KELLOOGs Then they'd be getting inte a region of steep lapse rate again. ‘Thirty-five siles. Tive had to cespress it because of the sise of the blackboard. This is the 35 afles here, end then we get « decrease of tenpera~ ture with height, and we have very good evidence for a lot of Ry DOE ARCHIVES
