<DIV><FONT size=3>Hello all.</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>We want to implement obs nudging in WRF for a retrospective case, but have not been able to convert DSS bufr data into little_r format.</FONT></DIV>
<DIV><FONT size=3>Here are the steps we followed to get the archived obs data in a WRF ready format.</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>1) We went to </FONT><A href="http://dss.ucar.edu/datasets/ds351.0/"><FONT size=3>http://dss.ucar.edu/datasets/ds351.0/</FONT></A><FONT size=3> and downloaded data and BUFR conversion software.</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>2) We compiled (tried gfortran and pgf90), created, and ran grabbufr using the grabbufr.sh script.</FONT></DIV>
<DIV><FONT size=3> - Ran successfully (we think) with pgf90 but gave warnings with gfortran.</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>3) Compiled (tried gfortran and pgf90), created, and ran bufr_upa2ob.x on the file created in step 2.</FONT></DIV>
<DIV><FONT size=3> - Exe's created.</FONT></DIV>
<DIV><FONT size=3> - Exe creates a file but program ends unexpectedly. Here is the screen output from bufr_upa2ob.x with error:</FONT></DIV>
<DIV><FONT size=3>-------------------------------------------------------------------------------</FONT></DIV>

<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>4) Went ahead and tried to run Yubao's perl script on the file produced in step 3.</FONT></DIV>
<DIV><FONT size=3> - Script runs, but the input file format is not what the script expects.</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>Any thoughts on how I can diagnose the problem?</FONT></DIV>
<DIV><FONT size=3></FONT> </DIV>
<DIV><FONT size=3>Thanks.</FONT></DIV>
