dₕ · outlet diameter
Sets port area and local airflow resistance; the effect on zₚ depends on the field state.

NOT COMPUTED · DATASET REQUIRED
U · synchronized airflow
Measure local air velocity at the external working field while T, RH, Ψs and the image timestamp are recorded.
Prediction / observationkeep sources separate
A dated image series locates the biological stopping front. It does not replace concurrent field measurements.

Lock the physical record before the run
Assign one specimen ID and register dₕ, zₕ, H, θ and surface profile on the Wall master.

εz stays pending until geometry, field, model output and dated observation share the same record.
