Supergranulation is one of the most visible length scales of solar convection and has been studied extensively by local helioseismology. We use synthetic data computed with the Seismic Propagation through Active Regions and Convection (SPARC) code to test time-distance inversions for supergranulation-like flows. The code simulates the acoustic wavefield in the presence of supergranulation-like background flows by solving the linearized three-dimensional Euler equations in Cartesian geometry. We model the supergranulation with a simple axisymmetric mass-conserving flow prescribed by the curl of a potential function. This work was supported by NASA contracts # NNH06CD84C and NNH07CD25C.
