|Abstract:||Fluctuations in the index of refraction in both the wet and dry components of the troposphere induce timing instabilities in radio metric data in excess of that of modern frequency standards. At zenith, the wet and dry tropospheres cause fluctuations of the order of 2 x 10-14 s/s and 7x 10-15 s/s at 1000 seconds, respectively. A description of the temporal and spatial characteristics of the wet and dry troposphere is given based on frozen flow modelling. The level of the fluctuations at various time scales and elevations is presented along with calibration strategies being investigated for both the wet and dry components.|
