In the CARRA system we have roughness at forecast time which is used in the model. This parameter is however unfortunately not archived in MARS.
We also have roughness lengths at analysis time which ARE archived in MARS. These are however climatological ones and not varying! We will omit including these for our daily/monthly products.
