Emily, The grid information you showed with LEVEL1 giving ****** and no vertical coordinate shown for the PMSL grid might mean that the grid coordinate was unknown- or that the $GEMTBL directory did not contain the correct parameter file. Can you run dcreanal again on the data set and provide me with any error messages that might have occured- or provide me with the source data file for me to look at here? Steve Chiswell
