The range correction calculated from ground-level meteorological measurements is shown to consist of a series of terms. The zeroth order term of this series corresponds to the correction obtained under the assumption of a spherically symmetric refractivity profile. The higher order terms arise due to departures from the spherical-symmetry assumption. The range correction is also shown to have residual errors, and an analytic expression for these errors is derived. Pertinent surface data are analyzed to obtain the magnitudes of the higher order corrections and the residual errors.
从地面气象测量计算出的距离修正显示为由一系列项组成。该系列的零阶项对应于在球对称折射剖面假设下获得的修正。高阶项是由于偏离球对称假设而产生的。还表明距离修正存在残余误差，并推导了这些误差的解析表达式。分析相关地面数据以获得高阶修正和残余误差的大小。
