Hey Bart,<br>
<br>
Since it wasn't the start and end date giving you problems, the other likely culprit would be that the restart file itself was generated from a time period outside of the start and end date that you've listed in the namelist. The way I understand the restart variable is that it generates a wrfrst file at the end of each interval specified in the namelist. That is, your restart interval is 18000 seconds, meaning that after 5 minutes from your start time, a restart file is generated. As your namelist sits now, you're trying to use a restart file that has no data for the 5 minute period you're trying to model, but has data for the next 5 minute period (assuming that the wrfrst file came from another run with the same start and end date).<br>
<br>
How long was your original model run that generated the restart file? As long as it was longer than, say 10 minutes, you should be able to use the restart file.<br>
