I suggest you write two descriptor files, one that is 6hourly from hour 0 to 174, and another that is 3hourly from hour 0 to 78. </div><div>—Jennifer</div><div><br></div><div><br></div><div><br><div><div>On Feb 14, 2015, at 6:38 AM, Syed Ahsan Ali <<a href="mailto:ahsanshah01@gmail.com">ahsanshah01@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">I have grib2 forecast files from 0 to 174 hrs having variable time<br>steps, 0 to 78 hours have 3-hourly files and next 6-hourly.
