@BeginDescription
The "afterburner" is the standard post processor for ECHAM data which provides the following operations:
@BeginItemize
@Item = Extract specified variables and levels
@Item = Compute derived variables
@Item = Transform spectral data to Gaussian grid representation
@Item = Vertical interpolation to pressure levels or height
@Item = Compute temporal means
@EndItemize
@EndDescription
@EndOperator


@BeginExample
To interpolate ECHAM hybrid model level data to pressure levels of 925, 850, 500 and 200 hPa, use:
@BeginVerbatim
   cdo after ifile ofile << EON
      TYPE=30  LEVEL=92500,85000,50000,20000
   EON
@EndVerbatim
@EndExample
