Abstract :
A method is described for predicting diurnal variation in uhf field strengths, which is based on the micrometeorology governing the nighttime refractive-index profiles. Using surface meteorological data from past years, predictions are made of the probability distribution of the diurnal field variations to be expected on 100 and 1,000 mc over CRPL links in Colorado. The predictions are compared with field-strength observations taken in 1952, and the agreement is encouraging.
