While DTM withdrew from geomagnetic research nearly six decades ago, its name still serves as a reminder of its historic role. Today, geomagnetic monitoring in the United States is the responsibility of the National Geomagnetism Program of the U.S. Geological Survey. The National Geophysical Data Center in Boulder, Colorado is the central agency archiving geomagnetic data from surface, ocean, airborne, and satellite measurement and making them available to the scientific community.
