Nodes of different colours represent the following:
Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses.

Threshold for computing sunshine duration (W/m2)
For sea ice, monthly values are based on Ebert and Curry, 1993, Table 2.
We take dry snow albedo as the representative value for non-summer
months, and bare sea-ice as the representative value for summer
months. The values for Antarctic are shifted six-months.

Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
