ESTIMATED RADIO REFRACTIVE INDEX IN THE TROPOSPHERE OF HANOI USING EXPERIMENTAL DATA FROM THE RADIO OCCULTATION AND RADIOSONDE METHODS
Keywords:
Radio refractive index, radio wave propagation, radio occultation, radiosonde.
Abstract
The article proposes a solution to use radio occultation and radiosonde data to estimate the atmospheric refractive index. The results show that the relative difference in radio refractivity between two methods changes from positive to negative, regardless of small or large altitudes, and has a magnitude of less than 4%.
