Switch to use the Robust Ecosystem Demography (RED).
This is based on :ref:`Argles, Arthur PK, et al.

``red_params.nml``
==================

This file contains a single namelist called :nml:lst:`JULES_RED` that sets parameters relevant to the `Robust Ecosystem Demography submodel (RED version 1.0) <https://gmd.copernicus.org/articles/13/4067/2020/>`_.
Activate RED using the :nml:mem:`JULES_VEGETATION::l_red` switch in :nml:lst:`JULES_VEGETATION`.

``JULES_RED`` namelist members
----------------------------------

.. nml:namelist:: JULES_RED

This namelist is used to read PFT parameters that are only needed by the Robust Ecosystem Demography (RED). Values are not used if RED is not selected.

.. note:: Where a quantity is said to have units of "/360days", this means that it is an amount per 360 days.

.. nml:group:: Only used when :nml:mem:`JULES_VEGETATION::l_red` = TRUE.

.. nml:member:: alpha_recrt

:type: real(npft)
:default: None

The fraction of PFT carbon assimilate devoted to reproduction.


.. nml:member:: crwn_area0

:type: real(npft)
:default: None

The lowest PFT crown area, value corresponds to the mass0 class (m\ :sup:`2`).


.. nml:member:: dom_order

:type: integer(npft)
:default: None

The value that describes the competitive hierarchy of PFTs competition in
JULES-RED, the higher the value the more dominant: 3 (trees), 2 (shrubs), 1 (grass).


.. nml:member:: height0

:type: real(npft)
:default: None

The lowest PFT height, value corresponds to the mass0 class (m).


.. nml:member:: lai_bal0

:type: real(npft)
:default: None

The lowest PFT balanced LAI, which corresponds to the mass0 class (m\ :sup:`2`/m\ :sup:`2`).


.. nml:member:: mass0

:type: real(npft)
:default: None

The lowest PFT mass class (kg C).


.. nml:member:: massi

:type: real(npft)
:default: None

The highest PFT mass class (kg C).


.. nml:member:: mclass

:type: integer(npft)
:default: None

Number of mass classes for each PFT.


.. nml:member:: mort_base

:type: real(npft)
:default: None

The baseline PFT mortality rate (/360 days).


.. nml:member:: phi_a

:type: real(npft)
:default: 0.50

The allometric/power scaling of PFT mass to PFT crown area (`West, G. B., et al 2009 <https://doi.org/10.1073/pnas.0812294106>`_).


.. nml:member:: phi_g

:type: real(npft)
:default: 0.75

The allometric/power scaling of PFT mass to PFT mass growth rate (`West, G. B., et al., 1997 <https://www.science.org/doi/10.1126/science.276.5309.122>`_).


.. nml:member:: phi_h

:type: real(npft)
:default: 0.25

The allometric/power scaling of PFT mass to PFT height (`Niklas, K. J., et al., 2001 <https://doi.org/10.1073/pnas.041590298>`_).


.. nml:member:: phi_l

:type: real(npft)
:default: 0.25

The allometric/power scaling of PFT mass to PFT leaf area index.

* Added a switch to allow interpretation of times in the model and the driving data as local solar time - see :nml:mem:`JULES_TIME::l_local_solar_time`. (#1327)
* Added a switch :nml:mem:`IMOGEN_RUN_LIST::l_drive_with_global_temps` so that JULES can be driven with global temperatures and climate patterns. (#1322)
* Added a switch ``l_drive_with_global_temps`` so that JULES can be driven with global temperatures and climate patterns. (#1322)
* Made Medlyn stomatal conductance, Farquhar C\ :sub:`3` photosynthesis, and thermal acclimation available in the UM. (#1246)
* Further work towards allowing layered soil carbon (:nml:mem:`JULES_SOIL_BIOGEOCHEM::l_layeredc` = TRUE ) in the UM. (#1237)
* A varying grey tile emissivity has been passed in to JULES - currently only available if selected in LFRic. (#1247)
