An expression is derived for the difference between the atmospheric refractive index calculated from the monthly averages of pressure, dry bulb temperature, and vapor pressure and as the average of the corresponding daily values. It is shown that the order of differences between them is negligible. The orders of errors introduced in the computed values of refractive index by rounding off the temperature and the pressure values to the nearest integral values are shown to be 2 to 3 N units.
