This guide is an addendum to the technical documentation of the ALADIN model. Its focuses on many physical processes linked to desert aerosols that are in the ALADIN code. This guide points out which modifications have to be made in the namelists and which main keys are needed in order to branch dust in the ALADIN prediction system and its post treatment.
During the FENNEC campaign, ALADIN-dust ran for more than thirty days in a row, with no observed bug. The model output was very useful (...)

The single column model (SCM) is the 1D version of th 3D ARPEGE-ALADIN operational model. It can be used for different purposes :
– make predictions in 3D model forced mode
– test the physical package on observational datasets as well as on idealized profiles
– Develop surface variational assimilation, while using tangent linear and adjoint versions of the SCM.
Since the SCM is a 1D version of the ARPEG-ALADIN 3D model, for which a documentation already exists, this documentation only briefly (...)
