Query: The StaggerGrid Project: a Grid of 3D Model Atmospheres for
  High-Precision Spectroscopy   In this contribution, we present the StaggerGrid, a collaborative project for
the construction of a comprehensive grid of time-dependent, three-dimensional
(3D), hydrodynamic model atmospheres of solar- and late-type stars with
different effective temperatures, surface gravities, and chemical compositions.
We illustrate the main characteristics of these 3D models and their effects on
the predicted strengths, wavelength-shifts, and shapes of spectral lines,
highlighting the differences with respect to calculations based on classical,
one-dimensional, hydrostatic models, and discuss some of their possible
applications to elemental abundance analysis of stellar spectra in the context
of large observational surveys.
