Virtual Magnetospheric Observatory

The Virtual Magnetospheric Observatory (VMO) is uniting a number of distributed repositories for magnetospheric data. VMO is a project within NASA's Heliophysics Data Environment and is maintained within the Heliospheric Physics Laboratory at NASA's Goddard Space Flight Center and the Institute of Geophysics and Planetary Physics at University of California, UCLA. The VMO utilizes the SPASE data model and provides uniform metadata for magnetospheric data sets. A prominent feature of the VMO are various query interfaces, which provide uniform access to the distributed data sets within VMO.

How Can You Find Magnetospheric 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.
Text SearchThe Text Search provides Google-like search experience.
Data Availability GraphThe Data Availability Graph displays when and how much data is available for each VMO resource. Resources can be hidden, re-arranged, time zoomed in or out, etc., and downloaded.
