Parameterization of Gravity Wave Mean-Flow Forcing

We have a parameterization that can be obtained via anonymous ftp. Versions written in both Fortran ("gwdrive.F" and sample input file "skyhi_in.dat") or IDL (gwdrive.pro) are available. This parameterization is suitable for application to GCMs or other coarse-resolution global models. For reference see Alexander and Dunkerton, 1999.
