Investigation of height coefficient in Arabian Gulf

In this paper, seventeen years of radiosonde meteorological data from 1997-2013 are analyzed for the subtropical Arabian Gulf region. The upper air refractivity, N_h, and vertical refractivity gradient, ΔN, are determined in the low troposphere using existing linear and exponential relationships in the literature. The study focusses on three layer heights at 65 m, 100 m and 1 km above ground level. The height coefficient parameter of the ITU exponential model has been investigated for each component in each layer, and considerable variation in this value is observed for each case. Correlation between the components of N_s with both N_h and ΔN are studied for each atmospheric layer.
