SPEDAS 3.00 now available!

The SPEDAS development team is pleased to announce the release of SPEDAS 3.00! The software is available as a zip file containing the IDL source code (which requires an IDL license to use), and also as pre-compiled executable files for Windows, Linux, and Mac.  The executable version supports the subset of features available via the SPEDAS Graphical User Interface, but requires no additional downloads or IDL licenses.


Where to get it

SPEDAS 3.00 can be downloaded from the SPEDAS web site:


Installation notes

There are a few platform-specific issues that may require additional steps after installation on the Mac and Windows 10 platforms:


What’s new?

SPEDAS 3.00 includes numerous bug fixes, efficiency enhancements, and new features:

New SECS (Spherical Elementary Currents System) plugin

A new plugin is available for the Spherical Elementary Currents System (SECS).  Two data types are available. The Equivalent Ionospheric Currents (EICS) are the horizontal currents and SEC Amplitudes (SECA) are the current amplitudesSummary plots can be generated in the SPEDAS GUI by selecting Tools->Overview Plots->SECS Overview Plots.

Command line crib sheets secs_load_data_crib.pro  and secs_mosaic_plot_crib.pro can be found in projects/secs/examples

New DSCOVR plugin

A new plugin is available for loading and plotting data from the DSCOVR mission. Summary plots can be generated in the SPEDAS GUI by selecting Tools->Overview Plots->DSCOVR Overview Plots.  Command line crib sheets dsc_crib.pro and dsc_mission_compare_crib.pro  can be found in projects/dscovr/examples

New GEOTAIL plugin

A new plugin is available for loading GEOTAIL data.  A command line crib sheet geotail_load_data_crib.pro can be found in projects/geotail.

Updates to THEMIS, ERG and IUGONET plugins
Updates to SPDF library to support HTTPS access to CDAWeb


New features in MMS plugin

– Added mms_flipbookify for creating “flipbook” style series of images with 2D FPI/HPCA distribution slices.  See mms_flipbook_crib.pro  in projects/mms/examples/advanced
– Added crib sheet that shows how to send MMS FGM and FEEPS data to Autoplot – mms_tplot2autoplot_crib (in projects/mms/examples/advanced)
– Updated FEEPS sun sector masks and active telescopes
– Updated mms_part_getspec to allow adding B-field/spacecraft ram directions to angular spectra
– Added initial overview plots to the SPEDAS GUI
– Added ability to subtract FPI distribution errors from prior to distribution calculations
– Added routine for creating MMS orbits plots (mms_orbit_plot)
– Added load routine for L3 merged FGM/SCM data products

Experimental new features (work in progress):

Download via HAPI (Heliophysics Application Program Interface)

A command line crib sheet crib_hapi.pro  can be found in general/examples

Import/export data to Autoplot

A command line crib sheet crib_tplot2ap can be found in general/spedas_tools/tplot2ap .  See also: mms_tplot2autoplot_crib in projects/mms/examples/advanced

Write CDFs from TPLOT variables with tplot2cdf
The tplot2cdf tool can be used to create CDF files (including most ISTP required variable attributes) from tplot variables.
A command line crib sheet crib_tplot2cdf_basic.pro  can be found in general/examples.  See also: mms_tplot2cdf_crib in projects/mms/examples
