Abstract : Theory indicates that the anomalous absorption produced during modification of the ionosphere by means of high power radio waves is dependent on the magnetic dip angle. Recent measurements of the anomalous absorption at Arecibo, Puerto Rico, are found to be considerably smaller in magnitude than those previously reported for the high latitude site at Tromso, Norway.
