 A decision was made to apply to the depth of the last hydrological node the same definition as the top one. That is, it is considered to be place at the bottom (or top) of the layer for numerical reasons. Thus the temperature node is put in the middle of the to and bottom hydrological layers.

+Model: ORCHIDEE Trunk (no STOMATE, with river routing)[[BR]]
+Forcing: CRU-NCEP/v5.3.2/twodeg[[BR]]
+Definition of vertical discretizations (VDs): [[BR]]
+VD1: 2m for water, 5m for temperature (trunk)[[BR]]
+VD2: 8m for water and temperature[[BR]]
+VD3: 2m for water, 8m for temperature[[BR]]
+Simulations: [[BR]]
+climatology simulations by repeating 1980-1989 for several loops[[BR]]
+VD1: 5*10 years[[BR]]
+VD2: 9*10 years[[BR]]
+VD3: 5*10 years[[BR]]
+
+
+Results: [[BR]]
+(1) Checking whether the spinup criteria (for soil moisture SM and soil temperature T) has been satisfied with different VDs.[[BR]]
+https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/Meetings/CMIP6/Physic/spinup_histograms.pdf​ [[BR]]
+
+Critetia1 for SM: (TMCend - TMCstard)/TMCmean,  with ±0.05 as threshold[[BR]]
+Critetia2 for SM: (MCend-MCstart)/0.005, with ±1 as threshold.[[BR]]
+Critetia for T: (Tend-Tstart), with ±0.1 as threshold. [[BR]]
+
+(2) The comparison of E, D, R, Ts, and H for the 3 VDs after spin-up (Annual, January, July, Amplitudes)[[BR]]

+The ET products include Jung, LandFluxEVAL, Fisher, and GLEAM.[[BR]]
+The maps are plotted for different seasons (MAM, JJA, SON, DJF, Annual).[[BR]]
+Figs. a-e are the ORCHIDEE reference value.[[BR]]
+Figs. f-j:   ORC - Jung[[BR]]
+Figs. k-o: ORC - LandFluxEVAL[[BR]]
+Figs. p-t:  ORC - Fisher[[BR]]
+Figs. u-y: ORC - GLEAM [[BR]]
+Zonal means coming soon !
