Dear WRF Users,
I'm having a problem to run wrf.exe with SST_update=1 and your help and
suggestions will be greatly appreciated. The SST data I'm using is the
RTG_SST 0.500 degree ( http://polar.ncep.noaa.gov/sst/). For boundary
conditions I'm using the NCEP FNL GFS data. I have 3 nested grids with
108, 36 and 12 km resolutions, running the model from 00:00 hrs of Jan.
01, 2010 to the 00:00 hrs of Jan. 15, 2010.
The steps followed to get to running wrf.exe are the following:
-Ran successfully geogri.exe
-Ran successfully ungrib.exe for the RTG_SST files.
-Ran successfully ungrib.exe for the FNL GFS files.
-Ran successfully metgrib.exe
-Ran successfully real.exe, creating wrfbdy_d01, wrfinput_d01,
wrfinput_d02, wrfinput_d03, and wrflowinp_d01, wrflowinp_d02, wrflowinp_d03.
When I ran wrf.exe, I get the following error:
Time in file: 2010-01-15_00:00:00
Time on domain: 2010-01-01_06:07:12
**WARNING** Time in input file not equal to time on domain **WARNING**

... Could not find matching time in input file wrflowinp_d01
-------------------------------------------
[cli_0]: aborting job:
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
Assuming that it could be an error of the time stamp on the input files,
I have checked the time stamp on the metgrid files and wrfbdy_d01,
wrflowinp_d0* (1 to 3), obtaining the following:
-Metgrib files: 2010-01-01_00:00:00to2010-01-15_00:00:00for nests 01, 02
& 03, every 6 hrs.
-wrfbdy_d01: 2010-01-01_00:00:00to2010-01-14_18:00:00 , every 6 hrs.
-wrflowinp_d0* (1 to 3): 2010-01-01_00:00:00to2010-01-15_00:00:00for
nests 01, 02 & 03, every 6 hrs.
I tried to change the end date in the namelist.input file to
2010-01-14_00:00:00 to run wrf.exe with the same wrfbdy_d01 and
wrflowinp_d0*, but I obtained a similar error.
Am I missing something on the namelist.wps or namelist.input files
(attached)?
I have search on the web, WRF user's forum, and the manual but I haven't
been able to find any solutions.
I also have a couple of questions about the input of SST data:
-I have only been able to run real.exe when I start the model at
00:00:00 hrs only, if I changed the start or end time to let say
06:00:00 hrs, I get an error. Do you know why that happens? Is that a
requirement to use SST data as input?
-For having a successful ungrib.exe run with SST data is it necessary 1
extra day of SST data as input, i.e. if your end date is
2010-01-15_00:00:00, you need the SST data until Jan. 16, 2010 to have a
successful run. This is just out of my curiosity to try to understand
better how WPS and WRF work in general.
Finally, when I remove the SST_update = 1, wrf.exe runs without any
problems.
Any help would be greatly appreciated!!!
