3.4 Selective namelists

In normal use, at each post-processing time step all the post-processing fields are written out at all post-processing levels and for all output (sub-)domains. However it is possible to specify a more selective list of fields to write out, by choosing for each field the exact list of post-processing levels, and for each post-processing level of each field the exact list of (sub-)domains.
    This is achieved by filling a specific namelist file currently named the selection file. In the local script the selection file should write : "xxtDDDDHHMM" where DDDD, HH and MM specify respectively the day (on 4 digits), the hour (on 2 digits) and the minute (on 2 digits) of the forecast. Furthermore in the local script the working directory should contain a file named dirlst listing the content of the working directory (as generated by the command %ls.
The selection files should contain the following namelist blocks :

 

1.

NAMFPPHY  

2.

NAMFPDY2  

3.

NAMFPDYP  

4.

NAMFPDYH  

5.

NAMFPDYV  

6.

NAMFPDYT  

7.

NAMFPDYS
