ATMOWeb ( as the part of FTPBrowser interface) provides a graphical browsing, subsetting and retrieval capability for selected ionospheric and atmospheric data. Data can be displayed as time series plots, filtering and scatter plot options are also included for a few spacecraft. The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

Plot and list heliocentric orbit information for spacecraft remote from Earth and for planets having heliophysics spacecraft in orbit about them. Underlying data files contain heliocentric distances and elevation and longitude angles at daily resolution. The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

The Heliocentric Trajectories Web services allow a software developer to use portions of the HelioWeb data in their own application. The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center. Besides direct access to the data and documentation, SPDF also provides web-based services for survey and high resolution data and trajectories. The Facility supports data from most NASA Heliophysics missions to promote correlative and collaborative research across discipline and mission boundaries.

This API allows any web application to offer an interactive 4D display of the trajectories of satellites known to SSCweb (Satellite Situation Center). The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA missions dealing with extremely energetic phenomena, from black holes to the Big Bang.

The National Space Science Data Center serves as the permanent archive for NASA space science mission data. 'Space science' means astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As permanent archive, NSSDC teams with NASA's discipline-specific space science 'active archives' which provide access to data to researchers and, in some cases, to the general public. Search by event, spacecraft, experiment, map, or publication query. NSSDC is part of the Solar System Exploration Data Services Office (SSEDSO) in the Solar System Exploration Division at NASA's Goddard Space Flight Center in Greenbelt, MD.

Physics of the Cosmos Program

This data set includes Voyager 2 Jupiter encounter magnetometer data given in Heliographic coordinates and averaged from the 60 ms instrument sample rate to a 9.6 second resampled rate. The data set consists of the following columns: 1) UT of the sample in the format yyyy-mm-ddThh:mm:ss.sssZ, 2) spacecraft clock (m65536:mod60:fds-line), 3) magnetometer id (1 = LFM, 2 = HFM), 4) Br (radial, Sun to spacecraft, B-field component), 5) Bt (azimuthal B-field component, positive in the direction of planetary orbital motion), 6) Bn (North/South B-field component, positive northward), 7) Bmag (magnitude of the averaged components), 8) avg_Bmag (average of the magnetic field magnitudes), 9) delta (latitude = arcsin(Bn/Bmag)), 10) lambda (longitude = 180. - atan(Bt/Br)), 11-13) rms vectors, 14) npts (number of points in average). All magnetic field observations are measured in nanoTesla. All of the magnetic field data are calibrated (see the instrument calibration description for more details).

The CDAWeb data service (at http://cdaweb.gsfc.nasa.gov) offers graphic, listing, subsetting and data computation services for a continuously increasing database of current and past Sun-Earth-Connections mission and ground-based data. As a complement to the CDAWeb data service, we also provide the publicly-released subset of the underlying database directly accessible as an anonymous FTP service (accessible at ftp://cdaweb.gsfc.nasa.gov). All data available from the FTP service are also available from CDAWeb itself; the major advantage of the FTP service is support for functions like mget.
