3.4.2.5 Troubleshooting
DKRZ GRIB/EXTRA Format Module Documentation
The afterburner package writes pure (unblocked) data files without any record information.
So don’t forget the pure (CRAY-2S) or the unblocked (CRAY-YMP) attribute in the assign statement
before reading it with the FORTRAN READ or the CRAY-FORTRAN BUFFER IN.If you read it using
fread an assign statement is not needed.
Check your namelist file, espacially for invalid codes, types and levels.
If all fails run the program with the Debug parameter mentioned above, e.g.
mod21 < namelistfile > myoutput inputdata outputdata Debug
Make the file myoutput readable for the public (using chmod 744 myoutput) and call the user support
group at the DKRZ.
3.4.2.6 Possible combinations of TYPE, CODE and MEAN
TYPE CODE MEAN
0-11 130 temperature
131 u-velocity
132 v-velocity
133 specific humidity
138 vorticity
148 streamfunction
149 velocity potential
152 ln p s
155 divergence
20-70 All codes 0/1
The four variables vorticity, divergence, streamfunction and velocity potential need special treatment if
the output on pressure levels (TYPE > 20) is selected. They are not available as TYPEs 30, 40 and 41.
If you select one of those combinations, TYPE is automatically switched to 70, 60 and 61 respectively.
