<DIV> </DIV>
<DIV>According to the WRFDA manual, the obs radar and obs ascii are the main input files for WRFDA. But I do not know how to convert the radar data and gauge data to WRFDA format (obs radar and obs ascii respectively). Any thought on how to fix this problem? </DIV>

<P class=MsoNormal>I have used the WRFDA with the online tutorial. However, now i have tried to make use the nimrod radar data as a input to WRFDA. The problem is how to convert this nimrod data to obs.radar and obs.ascii files. I noticed that these two files are the inputs to WRFDA. Am I right? The second question is how to get the data of reflectivity, beam height and so on.....Do you have any ideas on these issue? </P></DIV>

Some settings in your model might be wrong<BR>otherwise. However, terrain height may go negative over inland, for<BR>example, Imperial Valley (California), it is almost entirely below sea<BR>level-235 feet (72 metres) below at the edge of the Salton Sea, and<BR>Turpan Valley in Xingjiang, China, is below sea level 150 meters at the<BR>lowest area. I wonder if you check the locations of negative terrain<BR>heights and
see if they are located somewhere such as Imperial Valley.<BR>Hope this will be helpful.<BR>Feng<BR><BR><BR>-----Original Message-----<BR>From: <A href="mailto:wrf-users-bounces@ucar.edu" rel=nofollow target=_blank ymailto="mailto:wrf-users-bounces@ucar.edu">wrf-users-bounces@ucar.edu</A> [mailto:<A href="mailto:wrf-users-bounces@ucar.edu" rel=nofollow target=_blank ymailto="mailto:wrf-users-bounces@ucar.edu">wrf-users-bounces@ucar.edu</A>] On<BR>Behalf Of Aijun Xiu<BR>Sent: Wednesday, June 09, 2010 10:13 AM<BR>To: <A href="mailto:wrf-users@ucar.edu" rel=nofollow target=_blank ymailto="mailto:wrf-users@ucar.edu">wrf-users@ucar.edu</A><BR>Subject: [Wrf-users] terrain height<BR><BR>Hi,<BR> Is there anyone out there noticed the terrain height can go negative <BR>over Pacific ocean?
