Unzipping SST Data for Katrina tutorial

Postby danman21689 » Mon Jun 25, 2012 6:00 pm

I am having problems running the tutorial Katrina case when downloading the SST data on : http://www.mmm.ucar.edu/wrf/OnLineTutor ... ungrib.htm. These are the listed steps:

1. Download data and place in directory ../DATA/SST
3. ln -sf ungrib/Variable_Tables/Vtable.SST Vtable
4. ./link_grib.csh ../DATA/SST/rtg_sst_grb_0.5

After step 1, I use the gunzip command and then the tar -xf command. instead of giving me a directory like listed above in step 4 (rtg_sst_grib_0.5), it gives me these two files:


Any help would be amazing! Thanks!

Hi danman21689,

Data in .grb format is fine.
Now, simply create a directory to store the files in.
I guess, the '/DATA/SST' and also the filename are just example names.
Put the files in that directory and be sure to specify the correct path during step 4.

Your step 4 could look like this:
4. ./link_grib.csh /path/to/grib/files/*.grb

Good luck,

Hi danman21689,
I just encountered the same problem when trying to download the SST data from the ARW OnLine Tutorial webpage. It seems that the link doesn't include the actual sst data. I emailed WRFhelp about this problem so hopefully they will update the link. In the meantime, you can go to ftp://polar.ncep.noaa.gov/pub/history/sst
to get the required data (08/27/2005 - 09/01/2005).
Hope this helps,
