Metos3D (https://github.com/metos3d) is a software toolkit used for the computation of periodic steady states of biogeochemical and marine ecosystem models. Metos3D makes use of transport matrices. One major disadvantage of transport matrices is the fact that the used time step is hardcoded into each matrix. However, there is a possibility to alter the time step afterwards to some extent. We built in such a conversion technique into the 'metos3d' script using SciPy (https://www.scipy.org/). This technical report explains the details of the 'matrix' subcommand and its usage. 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8:1-zs-00000291-a1$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/macau_mods_00002015 5051 004
