Abstract

In this communication, nine years of local radiosonde meteorological data, from 1997 to 2005, have been used to calculate the vertical refractivity gradient, ΔΝ, in the lowest atmospheric layer above the ground surface. The values obtained are used to estimate the parameter β₀, which represents the probability of non-standard propagation. Hourly,monthly and yearly distributions of ΔΝ in the first 100 meters above the ground are given. Monthly and yearly variations of the mean of ΔΝ and β₀ are provided and the β₀ values are compared with the ITU maps.
