v6 v7 24 24 25 25 === hydrol.f90 === 26 Water budget closure is checked in hydrol.f90 for the related water stores (soil, snowpack and canopy) owing to the diagnostic variable ''TWBR'' (total water budget residu). This variable can be seen in the MONITORING tool when running with libIGCM.26 Since [https://forge.ipsl.jussieu.fr/orchidee/changeset/2720 r2720], water budget closure is checked in hydrol.f90 for the related water stores (soil, snowpack and canopy) owing to the diagnostic variable ''TWBR'' (total water budget residu). This variable can be seen in the MONITORING tool when running with libIGCM. 27 27 28 It is calculated at each time step as the difference between the total water storage change and the net fluxes, and should be close to zero if water is conserved. '''Acceptable values are in the o der of 10-13 kg/m2/s''' (~ less than 10^-8 kg/m2/d).28 It is calculated at each time step as the difference between the total water storage change and the net fluxes, and should be close to zero if water is conserved. '''Acceptable values are in the order of 10-13 kg/m2/s''' (~ less than 10^-8 kg/m2/d). 29 29 30 30 Another useful check variable is ''undermcr'', which is defined per soiltile, and holds the number of orchidee time steps per output time step in which at least one soil layer has a moisture content mc below the residual value mcr. These situations are pathological, since they are close to negative moisture contents, which make no physical sense and cannot be tracted correctly by the code. … … 34 34 === routing.f90 === 35 35 36 Note that TWBR does not tell anything about water conservation in the routing scheme. Instead, specific water budget residues are calculated for the 4 main reservoirs of the routing scheme: ''wbr_stream'', ''wbr_fast'', ''wbr_slow'', and ''wbr_lake''. The standard output unit is also in kg/m2/s, and these values must also be as close to zero as possible ('''DSG_review ADD RECOMMENDED VALUE for trunk revision XXXX''').36 Note that TWBR does not tell anything about water conservation in the routing scheme.

Explanations are [https://forge.ipsl.jussieu.fr/orchidee/wiki/Documentation/UserGuide/XIOSinConfig here]. 39 38 In the trunk (2.0), the output level for these variables is 8, so they are not exported by default (SECHIBA_HISTLEVEL = 5), and you need change the the output level to get them.
