Abstract

By combining the global atmospheric model NRLMSISE-00 and the humidity model of the Northern hemisphere (GOST 26352-84), we developed a model for calculation of the dielectric permittivity of the atmosphere along the radio-wave propagation path. Microwave radiometry data were used to test the model. The difference between the model and measured values of the zenith wet delay of radio waves in the troposphere averaged 1–3 cm for a r.m.s. deviation of 4.7–5.3 cm.
