| Zusammenfassung |
| The CSIRO Mk3L climate system model, a reduced-resolution coupled
general circulation model, has previously been described in this
journal. The model is configured for millennium scale or multiple
century scale simulations. This paper reports the impact of replacing
the relatively simple land surface scheme that is the default
parameterisation in Mk3L with a sophisticated land surface model that
simulates the terrestrial energy, water and carbon balance in a
physically and biologically consistent way. An evaluation of the new
model's near-surface climatology highlights strengths and weaknesses,
but overall the atmospheric variables, including the near-surface air
temperature and precipitation, are simulated well. The impact of the
more sophisticated land surface model on existing variables is
relatively small, but generally positive. More significantly, the new
land surface scheme allows an examination of surface carbon-related
quantities including net primary productivity which adds significantly
to the capacity of Mk3L. Overall, results demonstrate that this
reduced-resolution climate model is a good foundation for exploring
long time scale phenomena. The addition of the more sophisticated land
surface model enables an exploration of important Earth System
questions including land cover change and abrupt changes in
terrestrial carbon storage. |
