PURPOSE +!! ------- +!! The purpose of this routine is to compute the synthetic ZTD, ZHD, ZWD +!! +!!** METHOD +!! ------ +!! The delays are computed using the refractivity formula and its different +!! approximation. The delay can be separated in two parts. +!! The ZTD is the sum of the ZHD, including all component of the atmosphere, and +!! the ZWD, including the contribution of the non-dipolar moment of the molecule +!! of water vapor. +!! +!!
