First-Order Loss ================ First-Order Loss reactions take the form: .. math:: \ce{X} \rightarrow where :math:`\ce{X}` is the species being lost. First-Order loss rate constants are constant. A conforming implementation of version |version| of the configuration will provide ways to dynamically update wet deposition rates if nonconstant rates are needed. Input data for first-order loss reactions have the following format: .. tab-set:: .. tab-item:: YAML .. code-block:: yaml type: FIRST_ORDER_LOSS species: species name scaling factor: 1.2 .. tab-item:: JSON .. code-block:: json { "type": "FIRST_ORDER_LOSS", "species": "species name", "scaling factor": 1.2 } The key-value pair ``species`` is required, and its value must be the name of the species being removed by the reaction. The ``scaling factor`` is optional and can be used to set a constant scaling factor for the rate constant. When a ``scaling factor`` is not provided, it is assumed to be 1.0. All other data is optional and will be available to external modules during initialization. Rate constants are in units of :math:`(\mathrm{s}^{-1})`.
