Model state/output

The AeoLiS model state is described by a collection of spatial grid variables with at least one value per horizontal grid cell. Specific model state variables can also be subdivided over bed composition layers and/or grain size fractions. All model state variables can be part of the model netCDF4 output. The current model state variables are listed below.
