For each water property the user needs to define if it want or not to impose atmospheric fluxes. Here's an example of atmospheric properties that need to be defined -if the user wants to compute heat fluxes with standard bulk formulas-. The atmospheric properties are defined in the Atmospheric_x.dat input file. The heat (bulk formulas), mass and momentum fluxes are defined in the InterfaceWaterAir_x.dat. The example of an input file InterfaceWaterAir_x.dat is presented below.
WaterProperties_x.dat
For each property it's possible to impose an atmospheric (or surface) boundary condition. By default no atmospheric boundary condition is imposed (SURFACE_FLUXES : 0).
<beginproperty>
SURFACE_FLUXES : 1
<endproperty>
Atmospheric_x.dat
It's important to have the output of the atmospheric properties fields so the user can confirm what is being imposed
