Sec. 950.5  National Geophysical and Solar-Terrestrial Data Center 

(NGSDC).



    The National Geophysical and Solar-Terrestrial Data Center acquires, 

processes, archives, analyzes, and disseminates solid Earth and marine 

geophysical data as well as ionospheric, solar, and other space 

environment data; develops analytical, climatological, and descriptive 

products to meet user requirements; and provides facilities for World 

Data Center-A (Solid-Earth Geophysics, Solar Terrestrial Physics, and 

Glaciology).

    (a) Geophysical and solar-terrestrial data available from NGSDC 

include:

    (1) Marine geology and geophysics. Bathymetric measurement; seismic 

reflection profiles; gravimetric measurements; geomagnetic total field 

measurements; and geological data, including data on heat flow, cores, 

samples, and sediments.

    (2) Solar-Terrestrial physics. Ionosphere data, including ionograms, 

frequency plots, riometer and field-strength strip charts, and 

tabulations; solar activity data; geomagnetic variation data, including 

magnetograms; auroral data; cosmic ray data; and airglow data.

    (3) Seismology. Seismograms; accelerograms; digitized strong-motion 

accelerograms; earthquake data list (events since January 1900); 

earthquake data service with updates on a monthly basis.

    (4) Geomagnetic main field. Magnetic survey data and secular-change 

data tables.

    (b) Queries should be addressed to: National Geophysical and Solar-

Terrestrial Data Center, National Oceanic and Atmospheric 

Administration, Boulder, CO 80303, tel. 303-499-1000, ext. 6215.
