COMMENTS ON SOLAR ALPHA-PARTICLE CONTRIBUTIONS TO RIOMETER MEASUREMENTS.
Abstract
In a recent publication, Weir and Brown (J. Geophys. Res., 69(11), 2193-2198, 1964) calculated the effects of solar protons and a particles on riometers and concluded that, in cases where the alpha-proton ration is close to unity, 'the particles are responsible for more than 75 per cent of the ionospheric absorption,' and that 'solar a particle event' might be a more appropriate expression than 'solar proton event.' The purpose of this comment is to point out that their conclusions are the result of their choice of geomagnetic cutoff, that this cutoff is unrealistic from the standpoint of normal riometer work, and that solar alpha-particle dominance is rarely, if ever, observed.
