Hi Jacob-

The IDV does not have an export to GRIB (1 or 2) facility.  You can export
a particular display to a netCDF file that can be read back into the
IDV (and other programs that handle netCDF like ArcGrid).  Use the
Display's File->Save->Export Displayed Data.  If you want to make a volume
with a formula, then use the Export->Export Grid/Image to netCDF formula
by right clicking and selecting Evaluate.  All the grid subset information
(space, time) is maintained.
