The Virtual Heliospheric Observatory (VHO) is uniting a number of distributed repositories for heliospheric data. VHO is a project within NASA's Heliophysics Data Environment and is maintained within the Heliospheric Physics Laboratory at NASA's Goddard Space Flight Center. The VHO utilizes the SPASE data model and provides uniform metadata for heliopheric data sets. A prominent feature of the VHO is the query interface, which provides uniform access to the distributed data sets within VHO.
How Can You Find Heliospheric Data?
Number of search interfaces is available with various degree of complexity and flexibility. The quickest way to start may be with the search interface at the top of this page: Simply select the time range, region, and other constraints to get the desired data.
Available Search Interfaces
|Basic Relational Search||A sequence of simple menus offers a selection from available data resources.|
|Advanced Relational Search||Use the Advanced Relational query interface to build complex queries with multiple constraints, nested conditions, etc. Search conditions can include, for example, parameter values, space regions, or resource names.|
Where Else Can I Look for Data?
The best place to start looking for additional data resources is the Virtual Space Physics Observatory because it contains the most comprehensive list of space physics resources.
