数据描述

Heliophysics studies the nature and dynamic interactions of the Sun, the heliosphere, and the plasma environments of the planets and interstellar space. The Heliophysics Digital Resource Library (HDRL) archives and serves the heliophysics data, as a project in the Heliophysics Science Division (HSD) at NASA's Goddard Space Flight Center. Space Physics Data Facility (SPDF) is the active and permanent archive for the space physics data, while solar data is archived at Solar Data Analysis Center (SDAC), as components of the HDRL, per NASA’s Heliophysics Science Data Management Policy. SPDF provides multi-project, cross-disciplinary access to data to enable correlative and collaborative research across discipline and mission boundaries with present and past missions. The OMNI dataset provides cross-normalized solar wind field and plasma data mapped to the nose of the bow shock, geomagnetic and solar activity indices, and energetic particle flux data. COHOweb provides access to magnetic field, plasma, energetic particle, and spacecraft position data from many deep-space spacecraft (Voyager, Ulysses, STEREO, Pioneer, Helios, etc.).
