ISEE SUSANOO-SW data

Data Description

SUSANOO (Space-weather-forecast-Usable System Anchored by Numerical Operations and Observations) is a 3D MHD simulation based on observations of the Sun (Shita et al., 2014, Space Weather). ISEE SUSANOO-SW data includes the solar wind data simulated by SUSANOO, which are archived in the Common Data Format (CDF). The data files can be accessed with various data analysis software such as SPEDAS as well as with web browsers. The Quick look figures of the SUSANOO-SW are also archived.

Rules of the Road for Users of the ISEE-SUSANOO System Products

  1. Users should contact the ISEE-SUSANOO mailing list (chs-susanoo at isee.nagoya-u.ac.jp) before using the data for any publication or presentation that makes use of ISEE-SUSANOO data products.
  2. Publications that use the ISEE SUSANOO-SW data are required to cite the following reference: Shiota, D., et al. (2014), Inner heliosphere MHD modeling system applicable to space weather forecasting for the solar cycle 24 maximum, Space Weather, 12, 187. DOI: 10.1002/2013SW000989.
  3. All publications and presentations using the ISEE SUSANOO-SW data must include the following acknowledgement:
    "Data from the ISEE SUSANOO-SW were obtained from CIDAS at ISEE, Nagoya University (https://cidas.isee.nagoya-u.ac.jp/susanoo/)."
  4. Authors must clearly identify the version and DOI of the ISEE SUSANOO-SW data analyzed in their work. If the target journal has guidelines for Data Availability Statements, follow those rules. If no specific guidance exists, include the following statement in the Acknowledgements:
    "This study used the ISEE SUSANOO-SW data, version 01.01 (DOI: 10.34515/DATA_SUSANOO-00001)."
  5. The dataset is distributed under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
    Non-commercial scientific use is permitted under the above conditions. Redistribution or modification of the dataset itself is not allowed. Scientific analyses, processing, and visualization based on the dataset are permitted, provided that the original dataset is not redistributed in an altered form.
  6. The dataset is provided “as is” at the time of generation. The authors and copyright holders make no warranties, expressed or implied, and shall not be liable for any claims, damages, or other liabilities, whether in contract, tort, or otherwise, arising from or in connection with the dataset or its use.

In case of conflict, these Rules of the Road shall take precedence over the general CC license terms.

Data Format

Definition of Coordinate system for SUSANOO-SW data

  • Earth: Geocentric Solar Ecliptic (GSE)
    X is along the line from the Earth toward the Sun, and Z is parallel to the ecliptic pole.
    Y is on the ecliptic plane and completes the right-handed triad, which is opposite to the Earth motion.
    (e.g., see SSCWeb, https://sscweb.gsfc.nasa.gov/users_guide/Appendix_C.shtml)

  • Planets (except for Earth):
    X, Y, and Z are centered at each planet.
    X is the radial direction along the line from the Sun to Earth, and Z is perpendicular to the orbital plane. Y is a cross product of Z and X.

  • Spacecraft: Radial Tangential Normal (RTN)
    RTN system is centered at a spacecraft. X (R: radial) is along an unit vector from the Sun to a spacecraft. Y (T: tangential) is perpendicular to the spin axis of the Sun and X-axis. Z (N: normal) is the cross product of the X- and Y-axis.
