Greg, I have added an allow line for *.joss.ucar.edu for the IDD feedtype NMC2 on shemp.unidata.ucar.edu. For the eta216 data your request line should look like: request NMC2 "eta/alaska" shemp.unidata.ucar.edu Information on the 216 grid is found at: http://www.unidata.ucar.edu/staff/chiz/ncep_idd/eta216_files.html http://www.unidata.ucar.edu/staff/chiz/ncep_idd/eta216.html For dcgrib, a simple pattern works: NMC2 eta PIPE dcgrib ............etc.....
