* :code:`LSEDIMENTS` : to use the bottom sediments scheme of Flake (default)

* :code:`CSNOW_FLK` : snow scheme to be used. For the time being only option 'DEF' is active

* :code:`CFLK_FLUX` : scheme to be used to compute surface fluxes of moment, energy and water vapor:

  * 'DEF' : to activate the classic watflux 
  * 'FLAKE' : to use flake parameterization

* :code:`CFLK_ALB` : type of albedo for FLake.

  * 'UNIF' : a uniform value of 0.135 is used for water albedo
  * 'TA96' : :cite:t:`taylor_studies_1996` formula for water direct albedo, depending on solar zenith angle
  * 'MK10' : albedo from Marat Khairoutdinov

* :code:`LSKINTEMP` : flag to use or not the skin temperature computation.
