Scheme options
~~~~~~~~~~~~~~~~~

.. option:: CBLUse

	:Requirement:
		Required
	:Description:
		Determines whether a CBL slab model is used to calculate temperature and humidity.
	:Configuration:
		.. csv-table::
			:file: csv-table/CBLUse.csv
			:header-rows: 1
			:widths: 10 80


.. option:: SnowUse

	:Requirement:
		Required
	:Description:
		Determines whether the snow part of the model runs.
	:Configuration:
		.. csv-table::

.. option:: NetRadiationMethod

	:Requirement:

			:file: csv-table/NetRadiationMethod.csv
			:header-rows: 1
			:widths: 10 80


.. option:: BaseTMethod

	.. deprecated:: v2025a

		This option has been removed. The model now always uses weekday/weekend-specific
		base temperatures (``BaseT_Heating`` and ``BaseT_Cooling``) for HDD/CDD calculations.
		If present in legacy input files, this parameter is ignored.

	:Requirement:
		Optional (ignored)
	:Description:
		Previously determined method for base temperature used in HDD/CDD calculations.
		Now deprecated in favour of always using weekday/weekend-specific base temperatures.

.. option:: EmissionsMethod

	:Requirement:
		Required
	:Description:
		Determines method for QF calculation.

	.. note::

		Methods 11-46 include **biogenic CO2** calculations and are **experimental**.
		While scientifically validated against established photosynthesis models,
		users should verify results for their specific applications.
		See :ref:`SUEWS_BiogenCO2` for required parameters.
