Short summary
We describe a spectral nudging technique to constrain the large spatial structures of an atmospheric general circulation model (ACCESS1.3) towards an observational product (ERA-Interim). This has a number of applications for model development and scientific studies. This paper shows potential benefits of using the spectral nudging over the traditional Newtonian relaxation method.
