SDAC Data Finder

The SDAC Data Finder Page.


The Interface Region Imaging Spectrograph (IRIS) was launched on 27th June 2013.

  • Find out more about the mission at the NASA IRIS pages.
  • The IRIS Lockheed Martin Solar and Astrophysics Laboratory pages give many more details on mission operations, data, and IRIS data analysis.
  • IRIS data can be downloaded via the Virtual Solar Observatory.
  • IRIS data held at the SDAC is also available here.
    • Note: The SDAC archives both IRIS Level 1 and Level 2 data. IRIS Level 1 data is the highest non-irreversibly transformed data available. Software to promote IRIS Level 1 data to Level 2 data can be be found here. The IRIS team encourages the typical user to directly use IRIS Level 2 data which is fully calibrated. Details about the calibration steps involved can be found in De Pontieu et al. 2014 and Wuelser et al., 2018.


Hinode was launched on 22nd September 2006.
