Italian Center for Astronomical Archives
Some data archives listed here (LBT, TNG) are run by IA2, as well as others, which are listed at the bottom of their main page.
Infrared Science Archive (NASA/IPAC)
Contains data from numerous telescopes, including but not limited to WISE, 2MASS, Spitzer, and the Planck Telescope
Keck Observatory Archive (KOA)
For raw and reduced data from the Keck Telescope. Reduced data must be explicitly requested in the interface above the file list, otherwise only the raw images will be available
Data reduction tools
Large Binocular Telescope Archive
Raw data from the Large Binocular Telescope
Data reduction tools LBT Interferometer Archive
NOIRLab Astro Data Archive
Contains data from Kitt Peak, Bok, Cerro Tololo, SOAR, and WIYN Observatories
