SPEDAS Webinar!

This announcement just came out in the GEM Messenger. I'm re-posting it here as it's incredibly important if you are in the space physics community and use IDL (a programing language that many space physicist use to process, analyze and visualize data).

SPEDAS is a set of programs, functions, and procedures packaged together that are often used by the community. This project got it's start from the THEMIS project, and although I don't know the whole story, someone once told me that they figured we shouldn't keep re-invinting the wheel so why not share the programs often needed to process and display the data. Anyway, this program sharing project from THEMIS has grown and now includes many current missions, including BARREL.

Over the past umpteen years, THEMIS has held workshops at conferences to share how to use their software. This has been great, but always sort of geared for the beginner. I believe these new webinars will be for both beginners as well as starting to dive into the more advanced bits.

Anyway, if you are interested in learning more about SPEDAS, see the advert below.

Dear Space Physics community:

The Space Physics Environment Data Analysis Software (SPEDAS) development team would like to invite you to participate in two Webex presentations we'll be holding later this month.

On Wednesday August 24, at 10am Pacific time, we'll be hosting a tutorial, live demo, and Q & A session on the SPEDAS software package and its capabilities. For more information on SPEDAS please look at:  and

On Wednesday August 31 at 10am Pacific, we'll be hosting another session focusing on using SPEDAS to analyze MMS data. This MMS session will assume some familiarity with SPEDAS, so those who haven't used SPEDAS before might want to consider participating in both sessions. For more information on that software please see:

If there are any particular questions or topics of general interest that you'd like to see covered in either session, please send your suggestions to Jim Lewis,, and we'll try to work them in.

See below for agendas and Webex connection info.

Jim Lewis, Eric Grimes, Vassilis Angelopoulos and the SPEDAS team

SPEDAS Session:  SPEDAS general tutorial and live demo

Webex details:

Time: August 24 @10AM Pacific Daylight Time (scheduled for 2hrs) Meeting name = SPEDAS webinar Password = goSP3D@S Phone to use: 1-888-921-8686 Conference ID/pass = 3107947090 and press # International callers dial: 001-678-259-1049

Tentative agenda:
* SPEDAS overview and general concepts:  Missions supported, local and remote data repositories, load routines, data analysis and manipulation routines, tplot variables, plotting data, GUI capabilities
* Simple examples of using the command line to load data.
* Examples of how to access or modify the underlying data and metadata for tplot variables
* Plotting data with tplot (both line plots and spectrograms); changing tplot options
* Command line data manipulation routines: coordinate transformations, support data, data manipulation, use of the 'calc' routine to operate directly on tplot variables, crib sheets
* How to start the SPEDAS GUI;  how to import and plot existing tplot variables
* Loading data via the SPEDAS GUI: missions with SPEDAS plugins can be loaded via "Load Data" panel, other missions available via generic "Load Data from CDAWeb" panel.
* Plotting in the SPEDAS GUI;  how to change GUI plot options
* Data processing and analysis in the GUI: Data Analysis panel, summary plots, ISEE 3D tool, 'Calculate' panel
* Exporting GUI plots to postscript files for further editing or inclusion in papers.
