Title: Simulations of SUMER continuum observations
Abstract: We have performed radiation hydrodynamics simulations of the Solar chromosphere with the lower boundary velocity taken from MDI observations. The computed continuum intensity at $\lambda$1199Å is compared with SUMER observations that are co-temporal and co-spatial with the MDI observations. We find that large scale structures in the space-time diagrams of the observed intensity are well matched in the simulations. This means that these structures exist already at the response height of the MDI velocity.
