Abstract: The Near Infrared Imager and Slitless Spectrograph (NIRISS) is a contribution of the Canadian Space Agency to the James Webb Space Telescope (JWST). NIRISS has four observing modes: (1) Wide Field Slitless Spectroscopy (WFSS): low-resolution grism spectroscopy between 0.8 and 2.2 μm over the entire field of view. (2) Single Object Slitless Spectroscopy (SOSS): medium-resolution grism spectroscopy between 0.6 and 2.8 μm, optimized for time-series observations of transiting exoplanets. (3) Aperture Masking Interferometry (AMI): high angular resolution aperture masking interferometry between 2.8 and 4.8 μm. (4) Parallel imaging. Accurate simulations of each observing mode are necessary to prepare for the NIRISS commissioning phase, validate the JWST calibration pipeline, and to confirm the scientific potential of NIRISS. Here we present a summary of the tools developed by STScI to simulate JWST/NIRISS data and demonstrate how they can be used by the astronomical community to prepare for JWST observations.
