Diego, Here is something else you can try: Load the NARR data individual time steps. Then go to the IDV Dashboard, Field Selector tab and navigate to Formulas, Grids > Time Steps > Merge Time Sequences. Select the desired Display type (e.g., Color-filled contours) and click "Create Display". This will bring up a Field Selector dialog where you can "Add selected" fields from each individual time. Give that workflow a try. Keep us up-to-date on your progress.
