<div class="gmail_quote">All,<br><br>I'm having a problem using the GrADS Data Server (GrADS-DODS) from NCEP (NOMADS). I am using the sdfopen command to access the dataset (RTMA 2.5km). When I run the script locally on my Ubuntu machine, everything works great! However, when I transfered the script to my web host I get an error.<br>
<br>Here's the line from my script:<br>'sdfopen <a href="http://nomads.ncep.noaa.gov:9090/dods/rtma2p5/rtma2p5%27dapdate%27/rtma2p5_anl_%27currhr%27z" target="_blank">http://nomads.ncep.noaa.gov:9090/dods/rtma2p5/rtma2p5'dapdate'/rtma2p5_anl_'currhr'z</a>'<br>
(where dapdate=YYYYMMDD and currhr=HH - yes, I've double checked to make sure the data exists.)<br><br>Here's the output:<br>...<br>Running in Batch mode<br>No hardcopy metafile open<br>All files closed; all defined objects released;<br>

NetCDF: I/O failure<br>gadsdf: Couldn't ingest SDF metadata.<br>...<br><br>I've tried searching the web and this (excellent) mailing list assistance but I can't seem to figure out what's going wrong. I suspect it may have something to do with my web host. (I use Bluehost- I know they're a somewhat subpar host, but I'm just a student experimenting with different things!) <br>
<br>Here's what uname -a gives on my web server:<br>Linux <a href="http://box566.bluehost.com" target="_blank">box566.bluehost.com</a> 2.6.32-46.1.BHsmp #1 SMP Tue Sep 6 12:18:02 MDT 2011 x86_64 x86_64 x86_64 GNU/Linux<br>
<br>If there's other tests I can run to probe the issue, let me know. Also, is this the best way to use the GrADS-DODS server? Should I just download the grib2 locally instead?<br>
<br>I was planning to download the grib2 locally, but when I discovered the GrADS-DODS server I found out that this might not be necessary. I plan to run this script hourly, so please advise as to which method would be best.<br>
