+Analysis can be tricky as the graphical processing needs to interpret correctly the time dimension so that the curves are positioned on the time axis. The difference in representativeness of instantaneous and averaged values also needs to be illustrated in the graphics. The following choices were made for the original forcing data :
 - Instantaneous values are represented by symbols as in all rigour they are only valid as this point in time.
 - Mean fluxes are represented by horizontal lines over the period of validity of the value. This is the simplest assumption which can be made for average values.

 Two scalar variables (Tair and Qair) are compared as well as two fluxes (LWdown and SWdown). The Potential evaporation computed by ORCHIDEE is also shown as this is the most direct implication of the forcing on the model after precipitation. It allows to judge how strongly the errors made in the interpretation of the forcing will affect the functioning of the model.

 - The phasing of the diurnal cycle of the atmospheric variables is important in defining the potential evaporation.
 
+- This uncertainty on the potential evaporation is probably not as important as the one on precipitation, which was not tested here.

 - As demonstrated by the figures below the correct treatment of the diurnal cycle in orchideedriver results in much more comparable potential evaporation in ORCHIDEE. Or in other words dim2driver introduces differences which are not physical.
