Large- and Small-scale Dynamics and Meteor Studies in the MLT with a New-generation Meteor Radar on King George Island
Abstract: The project will employ a sophisticated meteor radar at the Brazilian Antarctic station Comandante Ferraz on King George Island for a number of synergetic research efforts of high interest to the international aeronomical community. The location of the radar will be at the tip of the Antar...
