Obtaining Recent Preliminary Data
The USGS Geomagnetism Program operates a downlink center in Golden, Colorado for the reception of geomagnetic observatory data via satellite and electronic file exchange. Golden is a Geomagnetic Information Node or GIN, which, as a member of Intermagnet, is one of several GINs located around the world.
Intermagnet data, which include those from USGS observatories, are available through the Intermagnet website on their Intermagnet Data Download page.
