. An intercomparison between 10 single-column (SCM) and 5 large-eddysimulation (LES) models is presented for a radiation fog case studyinspired by the Local andNon-local Fog Experiment (LANFEX) field campaign. Seven of the SCMs representsingle-column equivalents of operational numerical weatherprediction (NWP) models, whilst three are research-grade SCMs designedfor fog simulation, and the LESs are designed to reproduce in thebest manner currently possible the underlying physical processesgoverning fog formation. The LES model results are of variablequality and do not provide a consistent baseline against which tocompare the NWP models, particularly under high aerosol or clouddroplet number concentration (CDNC) conditions. The main SCM biasappears to be toward the overdevelopment of fog, i.e. fog which is toothick, although the inter-model variability is large. In realitythere is a subtle balance between water lost to the surface andwater condensed into fog, and the ability of a model to accuratelysimulate this process strongly determines the quality of itsforecast. Some NWP SCMs do not represent fundamental components ofthis process (e.g. cloud droplet sedimentation) and therefore arenaturally hampered in their ability to deliver accuratesimulations. Finally, we show that modelled fog development is assensitive to the shape of the cloud droplet size distribution, ararely studied or modified part of the microphysicalparameterisation, as it is to the underlying aerosol or CDNC.
