Default Top boundary in a entrainment atmospheric BL

Dear All,

How can I set a boundary condition on the top of a domain for atmospheric boundary layer which experience a radiative heat transfer (in Fluent)?

If I am correct, I need (at the top) a zero gradient for velocities, and a incident solar radiation, which is not readily available in Fluent. Radiation is only allowed in wall (unpermeable, which is not the case, because of boundary layer entrainment), inlet velocity, and others.

Which will be the most appropriate BC for my problem, and, if not available in Fluent, how can I implement it?

Thanks in advance, Reginaldo
