Hi Bryan,

I believe GDAL can do it.

http://www.gdal.org/

For example:

$ gdal_translate n0r_0.tif -of netCDF out.nc
$ ncdump -h out.nc
netcdf out {
dimensions:
         x = 6000 ;
         y = 2600 ;
variables:
         byte Band1(y, x) ;
                 Band1:long_name = "GDAL Band Number 1" ;

// global attributes:
                 :Conventions = "CF-1.0" ;
}

It doesn't appear to have kept the geo-referenced information tho...
