The Global Riometer Array, or GloRiA project is an attempt to unite the different riometry groups around the world (and their riometers) to provide a global overview of STP events. By providing a global overview of STP processes we will be in a better position to understand them. A world map shows the global distribution of riometers.
The GloRiA project has only just started. The first study is a global analysis of the ‘Bastille Day’ polar cap absorption event. To help visualise the temporal and spatial changes we have combined data from IRIS, CANOPUS (now NORSTAR), SGO and the University of Maryland riometer at Iqaluit to produce a movie.
