MDI Data Search and Export
MDI Data Search and Export Requests
These pages are still available to supply helpful historic information. All MDI data access
is now served from the JSOC pages at http://jsoc.stanford.edu in data series with names starting with "mdi.".
From this page you can search through
MDI and other datasets
available for export from the Solar
Oscillations Investigation (SOI) Data Archive, select and request
data to be exported (copied) directly to your machine/directory or via
various media formats, and check on the status of your request(s).
Choose the search and export
method that is easiest for you based on the kind of data you wish to export.
NOTE: Lev1.8 full-disk 96m magnetograms were recalibrated in December, 2008.
Calibrated magnetograms are available for download at our ftp site.
Thirteen annual ~14 Gb tar files provide the complete 96-minute magnetic series from 1996 - 2008.
Individual magnetograms can currently be retrieved at the same site from daily subdirectories.
All export requests for lev1.8 magnetograms (synoptic 96-minute and hourly one-minute campaigns) receive data calibrated
with the best available method.
See Lev 1.8 for a summary of the MDI magnetic field calibration.
- Daily Magnetograms and Synoptic Charts
Downloadable summary GIF images, fits files and daily synoptic charts.
Use this link if you are only interested in daily synoptic magnetic field data.
- Magnetic Field and Intensity Synoptic Charts
Downloadable synoptic chart fits files and gif images.
Use this link if you are only interested in synoptic charts (one per Carrington Rotation).
- Calibrated Data
Search for and export level 1.8/1.5 (or 1.7/1.4) MDI data (organized by observable,
e.g. full-disc dopplergrams, high-resolution magnetograms,
etc.), including campaign data. Use this link for most requests
for calibrated image data, particularly for time-series.
Campaign Data -
Search for and export level 1.5 MDI campaign data (organized in time-order by
campaign name). Cross referenced to SOHO
Use this link to find data for collaborative investigations. Sample images are provided.
- Calibrated Data by Time Range -
Search for and export any level 1.4/1.5/1.7/1.8 MDI data taken during a given range in time.
Use this link to find data if you know the time range you're interested in.
Also use this link for Spherical Harmonic Transform time-series.
- General Data
Requests - Search for and export any kind of data from the
SOI archive (organized by mission/instrument,
processing level, and data type). This is the most general of
our data export paths. Use this link if what you are looking for is not
in the above pages, or if you would like more information about the data
in the archive.
of Pending Data Requests -
Check on the status of your data export request.
