Abstract
A new formula relating the surface temperature and water vapor pressure to the wet-component range error is found based on an empirical exponential model of the vapor pressure as a function of height. It is pointed out that wet-component models based on the hydrostatic equation are probably invalid. The range error is proportional to the first power of the surface vapor pressure. The effective scale height varies with surface temperature and vapor pressure. Models are fit to 4 months of radiosonde measurements, and agreement to 1.4 cm (1 a) is obtained. However, in 2 of the 4 months, the standard deviation of the daily values about the observed monthly average is only slightly greater than the rms difference between the model and the measurements.
