Description:
Interest of the radio-meteorologist centers on diffusion because the vertical structure and the non-homogeneity of the atmosphere, in terms of refractive index, play a vital part in radar propagation. A portable method of measuring diffusion consists of lifting smoke-puff generators aloft with tethered balloons, setting off puffs remotely and photographing them with two motion picture cameras. From the resulting records of the areal spread of the smoke and the distance it travels, one may compute values of diffusion coefficients. Preliminary experiments yield data in accord with values published by Sutton.
