Jay, I just re-read your original email. I am working on a downscaling wind
model and had to read subsetted netcdf weather model files from NCEP via a
thredds server. At the time I was using GDAL to read and re-project
datasets. It did not support several cf projections, including lcc. So I
added them and it has been working well for me. like I said before, I don't
know when ESRI will start using the newest version. If you have more
questions with functionality in the gdal netcdf driver, let me know.
