Estimation of the ozone decrease possibility in the lower part of the <Emphasis Type="Italic">D</Emphasis> region under the action of a powerful radiowave

The possibility of the influence of a powerful radiowave on the ozone concentration in the lower part of the ionospheric D region is discussed on the basis of experiments at the Sura heating facility in March 2009, the results of which were published relatively recently by a group of authors. The results, which were obtained with the use of exact equations of the mesospheric ozone photochemistry, substantially disagree with some conclusions derived by the authors but do not completely deny their hypothesis on the possible influence on the ozone of internal gravity waves formed at heights of the ionospheric E region.
