Harry, The invalid grid message you are getting is that you have both grid 207 and grid 211 of the ngm trying to be written to the same file. The 211 grid is the [YZ].Q.*/mNGM and 207 is [YZ].N.*/mNGM. Its OK to use a single pattern action that matches all the different NGM grids in the data stream if you use the @@@ template in dcgrib so that the different grid projections will be written to different file names, eg: YYYYMMDDHH_ngm@@@.gem The other messsage about "skipped"is generally eaither thatthe parameter is not found in the $GEMTBL/grid/wmogrib2.tbl (parameter 2, vcoord 102, level 0)- which should be there, or that the tables weren't found with the GEMTBL environmental variable, or that the file was full. If the file is full, then we would want to increase the maximum number of grids allowed in the grid file with the -m option to dcgrib. The default is 1500 which should be sufficient unless more than the ngm is being written to the 211 file- such as eta grids sneaking in there too. We should double check the pqact.conf entry if that is the case.
