cdo conversion from model levels to height levels – in #13: Postprocessing

in #13: Postprocessing

<p> Hi all, <br/> in a post processing step I want to convert different variables of <span class="caps"> CCLM </span> output on model levels into values at fixed height levels. I tried the cdo command ml2hl without success. Unfortunately is the cdo documentation not really helpful. Is there anybody with an idea how I can do that with the <span class="caps"> CCLM </span> data? </p> <p> #—————————————————————————————————————————- </p> <p> These are the commands I used: </p> <p> cdo selname,P lffd2005071512.nc p.nc </p> <p> cdo ml2hl,4,20,50,100,200,400,800,1200,1600,2000,2500,3000,3500,4000 p.nc out.nc </p> <p> warning from cdo: cdo ml2hl (Warning): No data on hybrid model level found! </p> <p> #—————————————————————————————————————————- </p> <p> Regards Dirk </p>

Hi all,
in a post processing step I want to convert different variables of CCLM output on model levels into values at fixed height levels. I tried the cdo command ml2hl without success. Unfortunately is the cdo documentation not really helpful. Is there anybody with an idea how I can do that with the CCLM data?

These are the commands I used:

cdo selname,P lffd2005071512.nc p.nc

cdo ml2hl,4,20,50,100,200,400,800,1200,1600,2000,2500,3000,3500,4000 p.nc out.nc

warning from cdo: cdo ml2hl (Warning): No data on hybrid model level found!

<p> <span class="caps"> CDO </span> works only for hybrid levels. However, <span class="caps"> CCLM </span> is on terrain following height coordinates. <br/> Presently there is no official conversion routine for post processing. </p>

CDO works only for hybrid levels. However, CCLM is on terrain following height coordinates.
