Abstract:	We propose a new tropospheric mapping function for ground-to-air radio links. The mapping function is based on conventional approaches, as used in satellite navigation, but needs adapting to the specifics of terrestrial ranging. We validate the resulting mapping function using data from numerical weather models over an entire year. The new approach provides models of tropospheric delays that are accurate to within two centimeters, for elevation angles from 90 degrees down to 3.
