Measurements of Horizontal Variations of Radio Refractivity - First Results
Original language description
Horizontal variation of radio refractivity is addressed. A measurement campaign was performed by means of a remote controlled airship carrying sensors of temperature, pressure and humidity. The measurement was done over a 13 km long horizontal path at various heights. The path was partly over land and partly over water. The measurements show change of refractivity along the path caused mainly by change of relative humidity of air. Horizontal refractivity gradients calculated range between 0.75 N/km and2 N/km.
