| Zusammenfassung |
| Observations of high-resolution data on radio
refractivity were obtained by the airborne microwave refractometer over the
Indian sub-continent (a tropical country) from 1971 to 1988. Detailed vertical
and horizontal distributions of radio refractivity on a near-real-time basis in
the atmospheric boundary layer were determined . Radiosonde observations cannot
detect the thin refractivity gradients which characterize the propagation
environment in this low-altitude region. This knowledge is required to design
reliable and efficient communication systems for strategic, tactical and
operational needs. However, the results demonstrate the layer structures and the
variability of the boundary layer in time and space. The radio refractive
effects on electromagnetic propagation and the future direction of radio
refractivity fine-structure measurements are discussed. |
