ECHAM6 verification without top 10 layers synchronization and with less physics schemes

Verification of ECHAM6 nudging module when ECHAM6 has synchronized to its own outputs.

Some physics schemes are switched off as the following namelist was used.

&physctl
  LCOVER       = .false.
  lphys=.true.
  lconv=.false.
  lgwdrag=.false.
  lrad=.true.
  lsurf=.false.
  lvdiff=.false.
  lcond=.false.

ndg_197102.nc

ECHAM6 grb output converting to netcdf format as a reference data for ECHAM6 nudging module

diff_t_197102_gp_rmse.nc

Spatial root mean square errors on all levels and at all outputs (6 hourly).

RMSE between ECHAM6 output (echam6_nudging_grb_T63_197102.01_echam) and reference data (ndg_197102.nc)

namelist.echam

namelist used to run ECHAM6 nudging case, in which nudging is expected to only apply to layer 11 to 47.

Four ECHAM6 outputs when nudging module is switched on
