Short summary

Fog modelling remains a significant challenge due to the complex, interrelated physical processes involved, including microphysics. We evaluated the ability of an advanced microphysical scheme to reproduce the fog life cycle by comparing it with new vertical microphysical observations obtained using a tethered balloon during an extensive field campaign. Although realistic modelling performance was achieved, some biases remain that require further microphysics observations.
