You will need to copy the version 2 tables in $GEMTBL/grid from wmogrib2.tbl and ncepgrib2.tbl to wmogrib3.tbl and ncepgrib3.tbl. Then you should be able to decode your data. You should remove the 99110300.sst_gem file if its was created since it will not have the correct parameter information in it. Steve Chiswell
