The WFIRST Science Archive and Analysis Center

The Wide Field Infrared Survey Telescope (WFIRST) is a 2.4 m telescope with a large field of view (~ 0.3 deg²) and fine angular resolution (0.11''). WFIRST's Wide Field Instrument (WFI) will obtain images in the Z, Y, J, H, F184, W149 (wide) filter bands, and grism spectra of the same large field of view. The data volume of the WFIRST Science Archive is expected to reach a few Petabytes. We describe plans to enable users to find the data of interest and, if needed, to analyze the data in situ using sophisticated software tools provided by the archive. As preparation, we are building a mini-archive that will help us to define realistic science requirements and to design the full WFIRST Science Archive.
