Experiments:
1) Test the switch and BR when it is off:
Objective: Test that when we de-activate the use of the vertical structure function we get Bit-Identical results with the control branch from Gabor:
expid: gh9p (Tco639 dap_CY42R1_t2m_vertical_struct_Lswitch)   with L_VERT_CORR=.false
ctrl:    gh9h  (Tco639  dag_CY42R1_esuite) 
are bit-identical  on 2014060100-2014060112 
This shows that (i) the switch enables to switch off the use of the vertical structure function and (ii) the technical changes included in the branch are BI to the control dag branch.
2) Scientific evaluation when switch is on (use of vertical structure function):

CTRL: gh9h  (Tco639  dag_CY42R1_esuite), EXPT:  gh9i (Tco639 dap_CY42R1_t2m_vertical_struct_Lswitch)   20140601-20140930
CTRL: gh9q  (Tco639  dag_CY42R1_esuite), EXPT:  gh9r (Tco639 dap_CY42R1_t2m_vertical_struct_Lswitch)   20150601-20150930
For the EXPTs gh9i and gh9r the vertical correlation feedback was used (L_VERT_CORR=.true.) as specified by default in the script ssaana in /vol/ifs/sms

iver scores:
Winter (20150101 to 2015030920150330):  2 3 months and 9 days - expt still running:

Summer (20140601 to 2014081520140831) 2.5 3 months - expt still running:
file:///scratch/rd/dap/gh9h_gh9i/index.html
Impact summary:
  • Neutral impact for upper air analysis (also neutral OBSTAT differences).
