Hi Oscar,<br><br>For converting the observation data to LITTLE_R, we may need to know the format of LITTLE_R first. And the format specification can found in the following page:<br><br><a href="http://www.mmm.ucar.edu/mm5/documents/MM5_tut_Web_notes/OA/OA.htm">http://www.mmm.ucar.edu/mm5/documents/MM5_tut_Web_notes/OA/OA.htm</a><br>
<br>Following is the thing is my observation that may need to take care for using LITTLE_R with obsproc : <br>1. I am also new to Fortran, and see the there have Fortran I/O format column in this article. This field is analogy to the C printf formatting descriptor. e.g.<br>
<br>F20.5 = %20.5f<br>I10 = %10d<br>A40 = %40s<br><br>2. After realized the LITTLE_R format, another thing worth to mention is that, the 'platform' field in the report header seem important for obsproc.exe, as the following post said:<br>
<br><a href="http://mailman.ucar.edu/pipermail/wrf-users/2008/001009.html">http://mailman.ucar.edu/pipermail/wrf-users/2008/001009.html</a><br><br>3. In the report header, the fields '<br>- id', 'name', 'platform', 'source' need to have left alignment. <br>
- another fields need right alignment<br><br>For converting my data to LITTLE_R, i just write a program to scan my observation file and convert it to LITTLE_R.<br><br>*************************************************************************************************<br>
Back to my issue, <br>1. what is the meaning of NESTIX, NESTJX, NEXTI and NEXT fields graphically in the namelist.obsproc ?<br>2. For specify the domain of time in namelist.obsproc, what is the rule to fill the value of time_window_min, time_analysis and time_window_max ? Becasse i have an observation in LITTLE_R format, the range of date of the observation in this file is, let say 2005-02-28_15:00:00 to 2005-02-29_17:00:00, so i set<br>
<br>&record2<br> time_window_min = '2005-02-28_15:00:00',<br> time_analysis = '2005-02-29_16:00:00',<br> time_window_max = '2005-02-29_17:00:00',<br>/<br><br>but there have a line in command prompt shown the following:<br>
<br><br>Screwy NDATE: 2005-02-29_16:00:00<br>Screwy NDATE: 2005-02-29_17:00:00<br><br> Error: The time window [2005-02-28_15:00:00, 2005-02-29_17:00:00] does not menc 2005-02-29_16:00:00<br><br><br>Finally, no 3DVAR was generated. What is the problem of that, and is it have another field need to set for the time domain ?<br>
<br>Thank you very much,<br><br>Regards,<br>Patrick<br><br><div class="gmail_quote">On Sat, May 16, 2009 at 2:12 AM, Oscar Chimborazo <span dir="ltr"><<a href="mailto:ochimborazo@gmail.com">ochimborazo@gmail.com</a>></span> wrote:<br>

I have been looking for that information but without luck. If you can help me with this I would appreciate it very much.<br>

So i edit the file namelist.obsproc to make some configuration. obsproc.exe can read my LITTLE_R file, but the result at the bottom of this email was printed and no file like 3dvar file was generated. From the runtime log message of obsproc.exe, it shown all of the data are out of domain. I suspect that the record8 setting of namelist.obsproc was set incorrectly. What is the meaning of all of this field graphically ? Especially for the field, NESTIX, NESTJX, NEXTI and NEXTJ, because i don't catch the meaning of this from the ARW user guide.
