The distribution of radio refractive index structure parameter in boundary layers undergoing spatial or temporal transition


  • E. E. Gossard


The height distribution of Cϕ (the structure parameter of potential refractive index) in a steady, horizontally uniform boundary layer are calculated assuming power laws for meteorological quantities . The results are then compared with those of more rigorous models examined by Wyngaard et al. It is shown that the results are in very satisfactory agreement when the power is properly chosen. Finally, power-law profiles are used to calculate horizontal and temporal variations in vertical profiles of Cϕ and to calculate radio-duct thickness for several boundary transitional conditions.
