Webthe Longley-Rice model, there are three ways of specifying refractivity: You can enter the "Surface Refractivity" value directly, typically in the range of 250 to 400 N-units (corresponding to earth curvature values from 1.232 to 1.767). An effective earth curvature of 4/3 (=1.333) corresponds to a surface refractivity
