7 years ago Hi Cecile,
For these issues associated with bugs in the AMWG diags did you want to post them to the CESM_postprocessing github issues ( https://github.com/NCAR/CESM_postprocessing/issues) instead of the CESM-Development/CIME issues?
Thanks, Alice

A script for Taylor diagrams in the AMWG diagnostics package uses the pressure data for vertical interpolation for 300-mb zonal wind, and vertical weighted average of relative humidity and temperature. In the current script, “lev”, lev = po*(hyam+hybm), is used for pressure, but lev is not the actual pressure at each grid point.
Thus, pressure should be computed using the NCL function, pres_hybrid_ccm, which calculates pressure at hybrid levels [pres(i,j)=pohyam+ps(i,j)hybm]. Also, a variable at a specific pressure level should be calculated by a vertical interpolation function (vinth2p) and should not be a value at a closest pressure level.
