Users,<br><br>I work for NCEP on the team that supports the operational NOMADS site. We are in the process of adding a new product to GrADS-OpenDAP but are running into issues. I have included the syntax for the control file used below to make the index file. Once the control and index file are created I attempt to view the data plotted through grads. <br>
Here is the problem. I can not get the data to plot anything but a constant value on our sandbox nomads server or on my desktop. I can however see the plot successfully on our operational supercomputer. I have suspicions of the ulimit stack size, but have not been able to confirm this due to the test machines system constraints. So can anyone else get this data to successfully plot? If so please share your wisdom. Why does the exact same control file and grads version work on one system but not another?<br>
<br>The supercomputer is running grads version 2.0.a7 on AIX with ulimit -s of 4000000.<br>NOMADS sandbox is running 2.0.a3.p3 on LINUX with ulimit -s of 16832<br>I have downloaded both 2.0.2 and 2.0.a7 to my desktop (LINUX) with a ulimit -s 8000. <br>
<br>1. The grib2 file: rtgssthr_grb_0.083.grib2<br>which can be found for download under: <a href="http://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/sst.20130313/" target="_blank">http://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/sst.20130313/</a><br>
<br>2. The control file (sst.ctl) was created from g2ctl as follows:<br>dset rtgssthr_grb_0.083.grib2<br>index sst.idx<br>undef 9.999E+20<br>title /com/gfs/prod/sst.20130312/rtgssthr_grb_0.083.grib2<br>* produced by g2ctl v0.0.8.2<br>

<br>3. to create the index file I ran:<br>>gribmap -0 -v -i sst.ctl<br><br>4.To view the output<br>>grads<br>>d tmpsfc<br><br>As even more proof that I somewhat know what I am doing, I can successfully create a control and index file using the same steps as above and view pretty graphics for the half degree SST, rtgssthr_grb_0.5.grib2. <br>
<br>Thanks for any insight. <br clear="all"><br>-- <br><font><span style="color:rgb(102,102,102);font-family:georgia,serif">Carissa Klemmer
