Added option MULTI_LAYER_CONTROL = 4 to do this test, see commit [6357]

comment:3 Changed 2 years ago by alanso

Test were made with r6358.

Settings for the enerbil test:
MULTI_LAYER_CONTROL=4

Settings for mleb one layer case:
MULTI_LAYER_CONTROL=3

OK_GS_FEEDBACK=n
OK_HYDROL_ARCH=n
OK_IMPOSE_CAN_STRUCTURE=y
OK_MLEB=y

JNLVLE_OVER=0
JNLVLS=1
JNLVLS_CANOPY=1
JNLVLS_UNDER=0

The collapsed mleb scheme (i.e. run with 1 layer) could not reproduce the results obtained with enerbil. For longer runs, the largest deviation is seen for the sensible heat flux. The deviations are first observed in fluxsens and fluxlat during the first day of the simulations and then likely propagate to other variables.
