| Zusammenfassung |
Evaluating the models we use in prediction is important as it allows us
to identify uncertainties in prediction as well as guiding the priorities
for model development. This paper describes a set of benchmark tests that is
designed to quantify the performance of the land surface model that is used
in the UK Hadley Centre General Circulation Model (JULES: Joint UK Land
Environment Simulator). The tests are designed to assess the ability of the
model to reproduce the observed fluxes of water and carbon at the global and
regional spatial scale, and on a seasonal basis. Five datasets are used to
test the model: water and carbon dioxide fluxes from ten FLUXNET sites
covering the major global biomes, atmospheric carbon dioxide concentrations
at four representative stations from the global network, river flow from
seven catchments, the seasonal mean NDVI over the seven catchments and the
potential land cover of the globe (after the estimated anthropogenic changes
have been removed). The model is run in various configurations and results
are compared with the data.
A few examples are chosen to demonstrate the importance of using combined
use of observations of carbon and water fluxes in essential in order to
understand the causes of model errors. The benchmarking approach is suitable
for application to other global models. |
