Of the six sections of this first report, two deal specifically with the physics of the air and soil layer close to dry desert ground, because the general problem of energy conversion from insolation to heat can best be studied when the moisture factor is eliminated. The observations on which the discussion in Sections 1 and 5 are based were obtained at a site in the Peruvian desert, where the mean annual rainfall is measured as traces. The region includes climatic stations which hold the world record of dryness. Section 2 is concerned with small area meteorology under most humid conditions, in airflow over an inland lake. The investigation of details of wind structure around obstacles Sections 3 and 4 establishes connections to a broad range of related problems, from the tower bias of conventional anemometer exposure, to the structure of airflow between complicated roughness elements like the trees of a forest. For the last problem, that of airflow under plant canopies, offers new prospects of application, which will be followed up in the forthcoming final report. Author
