Substorm correlated absorption on a 3200 km trans-auroral hf propagation path...6.800 MHztransmissions were selected in order to determine the extent and occurrence ofauroral absorption....
K.: smallscale structure of ionospheric absorption of cosmic noise during pre-onset and sharp onset phases of an auroral absorption substormImpulsive pulsations of ionospheric absorption were found in imaging riometer measurements at Kilpisjärvi during the pre-onset and onset phases of auroral absorption substorms....
The statistical dependence of auroral absorption on geomagnetic and solar wind parametersData from the Imaging Riometer for Ionospheric Studies (IRIS) at Kilpisjärvi, Finland, have been compiled to form statistics of auroral absorption based on seven years of observations....
Unclassified/unlimited unclassified/unlimited morphology of southern hemisphere riometer auroral absorptionA morphology of riometer auroral absorption is derived from hourly values, determined at several Southern Hemisphere stations, located both near the centre of the auroral absorption zone and at higher...
