About Solar-Terrestrial Physics at NGDC

Much STP data are not represented on this web site. For example, many non-digital holdings including many millions of frames of ionograms, all-sky camera film, solar photographs, and 11,000 observatory years of magnetograms, are also archive at NGDC. Our digital holdings, also exceed our capacity to put them on-line [A history of STP].
