abstract. We inspect ground backscatter data from the Falkland Islands, Wallops Island and Blackstone radars for evidence of gravity wave activity. We comment on the interhemispheric nature of the gravity waves and their relationship to geomagnetic activity as inferred from the AL, AU, and Sym-H indices.
