Hi Keshab, You'll need to verify that the dattim and sfparm are being set correctly. For SFPARM = tmpf, for the file 2010032212_gmos.gem, for example, there exists forecasts for 100322/1800 100322/2100 100323/0000 100323/0300 and so on in 3-hr increments, with the last being 100325/1200 please note that for the file date, in this case "100322", because the gmos file is initialized at 1200, there only exists tmpf data for 1800 and 2100. If you adjust ${dd} up to the 23rd, 24th or perhaps the 25th, then 0000, 0300, 0600 and so on, will be available. Hope this helps.
