  NASA's Interface Region Imaging Spectrograph (IRIS) provides high resolution
observations of the solar atmosphere through UV spectroscopy and imaging. Since
the launch of IRIS in June 2013, we have conducted systematic observation
campaigns in coordination with the Swedish 1-m Solar Telescope (SST) on La
Palma. The SST provides complementary high-resolution observations of the
photosphere and chromosphere. The SST observations include spectro-polarimetric
imaging in photospheric Fe I lines and spectrally-resolved imaging in the
chromospheric Ca II 8542 A, H-alpha, and Ca II K lines. We present a database
of co-aligned IRIS and SST datasets that is open for analysis to the scientific
community. The database covers a variety of targets including active regions,
sunspots, plage, quiet Sun, and coronal holes.
