A tropospheric signal delay model for radio astronomical observations

Molera Calvés, G.; Duev, D. A.; Pogrebenko, S. V.

In this work, a three-dimensional refraction model is proposed, which allows one to calculate the delay of signal due to the Earth's troposphere—the main source of error limiting the accuracy of modern radio astronomical observations. The method of raytracing through the three-dimensional troposphere (numerical weather model) is used. The results …
