2.2.0 spase://SMWG/Observatory/SuperMAG SuperMAG 2010-08-05T18:19:17Z The SuperMAG program involves a collaboration of more than 200 ground geomagnetic observatories coordinated by JHU/APL. A heterogenous ensemble of ground station data are made homogeneous by conversions to a common time resolution (1 min) and a common coordinate system (NEZ), by baseline removal, and by data cleanings. Resultant data are intended for studies of varying ionospheric and magnetospheric current systems. spase://SMWG/Person/Jesper.W.Gjerloev PrincipalInvestigator SuperMAG web page at JHU_APL http://supermag.jhuapl.edu/ Earth.Surface
