The following theoretical Part I and experimental Part II studies have been carried out I. Theory The exact mathematical formulations of the eddy viscosity and the eddy diffusity were derived in the frame of mixing length concept. This allowed clarification of the repeatedly discussed mutual interdependency of these quantities, which is relevant to comparison of their fundamental transport mechanism. Moreover, several basic relationships that are relevant to the understanding of the parameters entering the treatise and useful for the evaluation of respective data measured were elaborated. A theoretical justification is given of the confinement of the measurements to the use of the emanations as tracers for the atmospheric eddy transport. Special labor was spent on the development, design and testing of two new equipments The transportable arrangement measuring atmospheric mass and momentum transfer, and the still stationary arrangement measuring atmospheric eddy conductivity, correcting directly distortions by atmospheric humidity. A device evaluating the measured thoron profiles directly into relevant and final data by electronic means has been designed and manufactured.
