Analysis Software SPEDAS/UDAS

SPEDAS (Space Physics Environment Data Analysis Software) is a set of IDL (Interactive Data Language) libraries that provides an integrated analysis platform for Solar-Terrestrial Physics. UDAS is one of the plug-in for SPEDAS.


SPEDAS has useful features as follows:

  1. Automatic data download without specifying the data's location

  2. Data analysis without regard to the file format of the data

  3. Parallel display of different types of data from many satellite and ground-based missions, including IUGONET.

  4. Utilization of various analysis functions equipped in SPEDAS (e.g., frequency analysis, filtering)

  5. Output into an ASCII file or image files (e.g., PNG, JPEG, GIF)

  6. GUI available for those new to IDL and SPEDAS

  7. SPEDAS-GUI executable on the IDL Virtual Machine without a paid IDL license.

UDAS egg

UDAS egg (UDAS Easy Guide to Generate your load routines) provides users with the templates for IDL procedures that can load your own data files into SPEDAS/IDL. According to the document, the users can easily create the load procedure for their own data by modifying the template procedure (about 10 lines identified in this routine). It supports Windows, Linux, and Macintosh. It's easy to use!

Notice

  1. SPEDAS and UDAS have been tested on IDL 6.3-8.5.
  2. When you use the IUGONET data, please check the data policy for each data set. The data use policy will be displayed in the console, when you load the data on IDL.
  3. Any analysis software can be used free only for academic purposes. When you use the UDAS and UDAS egg, please refer to the rules of the road of the IUGONET project.
  4. IUGONET do not take any responsibility or liability for any damage or loss caused by the routine you customized.
  5. Some routines are dependent on ERG Plug-in (ERG Science Center: https://ergsc.isee.nagoya-u.ac.jp/index.shtml.en), please also install ERG-SC plugin if you manually update UDAS.
