Spectral Interdependence of the Radio Refractivity and Water Vapor in the Atmosphere

Continuous measurements of temperature, water vapor, and radio refractivity were taken over several days at a height of 11 meters above ground over the high plains of Colorado. A spectral analysis indicates that temperature fluctuations contribute little to radio refractivity fluctuations, which are primarily caused by variations in water vapor density over a wide range of spectral frequencies.
