Hi,<br><br>I am using the WRFDA package, and converted my own observation data to LITTLE_R format and try to process it using the obsproc.exe. 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&#39;t catch the meaning of this from the ARW user guide. Thank very much ~<br>
