8.7 Example: ECMWF meteo extracted from MARS archive

This section describes the settings to extract meteo from the MARS archive at run time. Usefull when running TM5 as preprocessor.

8.7.1 Setup files

To retrieve grib files from the MARS archive, use for example the following settings in the rcfile:

        tmm.setup.001.apply    :  T
        tmm.setup.001.files    :  CVL/CVH/TVL/TVH/Z/LSM/SR/AL/LSRH
        tmm.setup.001.sources  :  ecmwf-mars:class=od;type=an;levs=sfc;grid=N80
        tmm.setup.001.search   :  
        !
        tmm.setup.002.apply    :  T
        tmm.setup.002.files    :  SP/CI/SSTK/SWVL1/SWVL2/SWVL3/SWVL4/10FG/SD/LSP/CP/SF/SSHF/SLHF/BLH/10U/10V/2T/2D/SSR/EWSS/NSSS/SRC
        tmm.setup.002.sources  :  ecmwf-mars:class=od;type=fc;levs=sfc;grid=N80
        tmm.setup.002.search   :  
        !
        tmm.setup.003.apply    :  T
        tmm.setup.003.files    :  LNSP/VO/D
        tmm.setup.003.sources  :  ecmwf-mars:class=od;type=fc;levs=ml60;grid=T159
        tmm.setup.003.search   :  
        !
        tmm.setup.004.apply    :  T
        tmm.setup.004.files    :  T/Q/W/CLWC/CIWC/CC/104.128/105.128/106.128/107.128
        tmm.setup.004.sources  :  ecmwf-mars:class=od;type=fc;levs=ml60;grid=N80
        tmm.setup.004.search   :

Some specialties:

• To extract meteo archived fro a special experiment, use:

   
            tmm.setup.001.sources  :  ecmwf-mars:class=od;type=an;levs=sfc;grid=N80;expver=500
  

• Convective fields for the gems 2002/2003 extension to era40 are archived by their grib table and code:

   
            tmm.setup.004.files    :  104.128/105.128/106.128/107.128
            tmm.setup.004.sources  :  ecmwf-mars:class=od;type=fc;levs=ml60;grid=N80;expver=500
  

8.7.2 Sourcekeys

The read the files into TM5, use for example the following source keys:

        tmm.sourcekey.glb3x2.*         : ecmwf-mars:class=e4;type=fc;levs=ml60;gg=80;tres=_fc012up2tr3
        tmm.sourcekey.glb3x2.convec    : ecmwf-mars:class=e4;type=fc;levs=ml60;gg=80;tres=_fc012up2tr3;method=ec-ll

        tmm.sourcekey.glb1x1.*         : ecmwf-mars:class=e4;type=fc;levs=sfc;gg=80;tres=_fc012up2tr3
        tmm.sourcekey.glb1x1.oro       : ecmwf-mars:class=e4;type=an;levs=sfc;gg=80
        tmm.sourcekey.glb1x1.lsm       : ecmwf-mars:class=e4;type=an;levs=sfc;gg=80
        tmm.sourcekey.glb1x1.veg       : ecmwf-mars:class=e4;type=an;levs=sfc;gg=80;tres=_an0tr6
        tmm.sourcekey.glb1x1.sr        : ecmwf-mars:class=e4;type=an;levs=sfc;gg=80;tres=_an0tr6
        tmm.sourcekey.glb1x1.albedo    : ecmwf-mars:class=e4;type=an;levs=sfc;gg=80;tres=_an0tr6
        tmm.sourcekey.glb1x1.sps       : ecmwf-mars:class=e4;type=fc;levs=ml60;gg=80;tres=_fc012up2tr3
