Radio wave pulse echoes can be utilized for continuous recording of all meteorological discontinuities to the base of the stratosphere. Both operations and preliminary theory show that extremely weak reflections are superimposed upon a continuous pulse reflection background up to the base of the stratosphere. This allows observation of almost infinitesimal reflection variations as humps on the general reflection background of reflection coefficient about 10−6 to 10−7 (when 123 meter waves are used). New equipment to replace this now obsolete station awaits utilization.
