Radiation on slopes¶
Correct parameterization of incoming radiations for homogeneous explicit slopes
! This parameterization considers there is an homogeneous and infinite slope.
! It replaces the parameterization LNOSOF = FALSE which is wrong in that case
! (I do not know if LNOSOF = FALSE parameterization is correct in some
! other SURFEX configurations).
! The LSLOPE parameterization must be used when the shortwave direct radiation has already
! been projected on the slope.
! The incoming diffuse shortwave and longwave radiations are horizontal and isotropic.
! The modifications of these fluxes is only due to a sky view factor which is estimated for
! an infinite slope.
! The longwave radiation of the complementary solid angle is computed assuming
! the surface of the opposite slopes have the same temperature.
! The shortwave radiation reflected by the opposite slopes are neglected.
! Do not modify the direct radiation which must be projected in the forcing file.
Date of start of development¶
Commit number before the development¶
Current status (in progress, or commit number in cen_dev or cen_release) and expected schedule¶
Stable in branches cen and cen_release
Evaluated against SURFEX test database ? yes or no¶
New test added in the database (if yes, describe)¶
To be done (M. Fructus)
Changes in namelist¶
LSLOPE = True
Define all possible values for each modified or created namelist keys
Other required changes (forcing files, snowtools code or options, VORTEX, ....)¶
Forcing files must have the radiations projected on the slopes.
This is the case if the sloppy forcing is generated by snowtools_git.
This can not be the case with old forcing files.
