Virtual Heliospheric Observatory

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.

The VHO actively collaborates with the Virtual Energetic Particle Observatory and the Virtual Waves Observatory to enable access to energetic particle and waves data, respectively.

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 SearchA sequence of simple menus offers a selection from available data resources.
Advanced Relational SearchUse 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.
Data Availability GraphThe Data Availability Graph displays when and how much data is available for each VHO resource. Resources can be hidden, re-arranged, time zoomed in or out, etc., and downloaded.
