    294294> '''AD(22/06/2106)''': this is very encouraging, thank you for all this work. Yet, some little questions remain. When looking at the plot in the above link, which seem to correspond to a grid-point touching the one at which the above image was obtained, I see different wind speeds, RadT and EPot for the two CRU-NCEP simulations. The difference in wind can explain the aother differences, but why is the wind different?

     296= Update from the Earth2Observe Project = 
     297 
     298In the framework of the Earth2Observe project three models (JULES, ISBA and ORCHIDEE) have compared the way they reconstruct the diurnal cycle from the 3hourly E2OFD. 
     299Please not that Jules has only provided hourly values and thus there is small shift at strong changes.

     301A few things can be noted in [https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/Branches/Driver_Improvements/Graphics_ALL_E2OFD.pdf] : 
     302 
     303- The SWdown is quite different in all 3 models. Only ORCHIDEE tries to generate a diurnal cycle using the solar zenithal angle. 
     304 
     305- The scalar are interpolated in exactly the same way. 
     306 
     307- There is a time shift in the radiation fluxes produced by ISBA related to the difficulties exposed above.
