Virtual Energetic Particle Observatory support for ground-based neutron monitor data products
Abstract
The Virtual Energetic Particle Observatory (VEPO) is a subdiscipline focus group of NASA's Virtual Heliospheric Observatory (VHO) and supports the identification, conditioning, registra-tion, and on-line access for heliospheric and solar energetic particle data products of potentially wide interest to the U.S. and international research communities. All VEPO data products are documented with metadata in the standard Space Physics Archive Search and Extract (SPASE) language. Primary data products planned to be served by VEPO are from spacecraft including the Advanced Composition Explorer (ACE), Helios 12, IMP-8, Pioneer 1011, SOHO, Stereo AB, Ulysses, Voyager 12, and Wind that have operated, or continue to operate, in interplan-etary space outside the Earth's magnetosphere. It has long been recognized, however, that investigations of cosmic ray modulation in the heliosphere, and detection of the most energetic particles from solar events, require the higher energy ranges of ground-based instruments such as neutron monitors for correlation to lower-energy measurements from spacecraft. In order to bring greater visibility to neutron monitor data for the needed correlation to spacecraft data for cosmic ray studies, we have implemented VEPO and VHO support for an initial set of neutron monitor data products. This searchable inventory will be expanded to bring more neutron-monitor and other ground-based data into the virtual observatory data environment.
