In my purpose,After 20 years simulation ,I want to make a file which contain variable of 20 years month by month,time interval is one month!I think postprocss can do this by using

        .true.,   ! Continually average ATM data b/twn idate&idate2?         
         -1.,   ! No. Days for continual averaging (-1=monthly;1=daily;5=5day) and I use RegCM3.1

      so,I do as following:

        cp ../PostProc/postproc.f .

         cp ../PostProc/postproc.param .

        cp ../PostProc/postproc.in . 

       cp ../PostProc/postproc1.param .

then,change the nyf,nxf as domain.param,

then

    cp Makefile_PGF5 Makefile

  Here,In the former module,I use Makefile_PGI5,but there is no Makefile_PGI5

,Is  Makefile_PGF5 using here right?

  then,

      pgf77 -byteswapio -o postproc pstproc.f

but it is not successful,

        [root@localhost 11]# cp Makefile_PGF5 Makefile
[root@localhost 11]# pgf77 -byteswapio -o postproc postproc.f

   I am looking for those lines,found those may all related to "iachar" and "trim",but I don't  konw how to modify them?what is the reason?

  And I want to konw is there other parts I need notice in postproc?

 I am sorry for a so long e-mail!Hope for your reply! Thank you in advance!Good luck! 

Your Sincerely,
