Based on the data of 5 years in 1970s with duct present and those of December 1990, refractivity at height of 1 km, the average gradient of refractivity and surface refractivity are obtained by regression of the refractivity profiles to exponential models. And it is found that the constants in the exponential relation of refractivity of 1 km above ground and the mean vertical refractivity gradient in the first kilometer height with the surface value of refractivity are 110.6, 0.002 9 and -8.6, 0.004 7 respectively according the data of the 1970s?
