Abstract :
The Atmospheric Boundary Layer (ABL) which forms the lowest 1-2 km portion of the earth´s environment has a significant role in the field of communications. In order to study the dynamical behaviour of the ABL and its effect on microwave propagation characteristics, a monostatic SODAR is developed with an operating frequency of 2.2 KHz and a probing range of 1 km. The system is in operation since July 1987 and has revealed various types of ABL phenomena. The effect of the inversions on the propagation of microwaves in the ABL is studied.
