The analysis of spherically layering calculated results shows that the variation of atmospheric path delay ( especially wet term) with zenith angle obeys well the secant law.

Base on these calculations and the surface meteorological parameters, the local year and month correction models of dry delay at the zenith angle of 0 are established by statistical methods.
