Space Physics Archive Search and Extract (SPASE) is a NASA-coordinated effort, with extra-NASA U.S. andinternational participation, intended to facilitate the finding, retrieval and usage of increasinglydistributed heliophysics data and related resources.
The primary focus of the first years of SPASE has been the development of the “SPASE Data Model,” thespecification of (a) terms (fields) with which heliophysics data and related resources are to be describedand (b) for each of many terms, a list of valid values.
The list of data and related resources for which specifications of terms and valid values have been made is currently:
A full description of the SPASE Data Model, as well as tools to help in the creation and validation of SPASE descriptions, can be found at http://www.spase-group.org/.
SPASE-compliant, VEPO-relevant descriptions have in common that the Data Model term “Measurement Type” has the value “Energetic Particles” from this term’s list of valid values.
SPASE descriptors of VEPO-relevant data and other resources may be viewed through VHO. After retrieving a list of data granules satisfying query criteria, click on the ”?” immediately following the granule name. This provides a listing of all relevant descriptors (granule, parent data product, relevant instrument and repository, etc.) in VHO formatting. Original xml-formatted descriptors may be viewed by clicking on the “xml” boxes shown in the VHO-formatted descriptors.
