Beschreibung:
We present a generalized framework for assessing the skill of global upper ocean
ecosystem-biogeochemical models against in-situ field data and satellite observations.
We illustrate the approach utilizing a multi-decade (1979-2004) hindcast experiment
conducted with the Community Climate System Model (CCSM-3) ocean carbon model.
The CCSM-3 ocean carbon model incorporates a multi-nutrient, multi-phytoplankton
functional group ecosystem module coupled with a carbon, oxygen, nitrogen,
phosphorus, silicon, and iron biogeochemistry module embedded in a global, threedimensional
ocean general circulation model. The model is forced with physical climate
forcing from atmospheric reanalysis and satellite data products and time-varying
atmospheric dust deposition. Data-based skill metrics are used to evaluate the simulated
time-mean spatial patterns, seasonal cycle amplitude and phase, and subannual to
interannual variability. Evaluation data include: sea surface temperature and mixed layer
depth; satellite derived surface ocean chlorophyll, primary productivity, phytoplankton
growth rate and carbon biomass; large-scale climatologies of surface nutrients, pCO2, and
air-sea CO2 and O2 flux; and time-series data from the Joint Global Ocean Flux Study
(JGOFS). Where the data is sufficient, we construct quantitative skill metrics using:
model-data residuals, time-space correlation, root mean square error, and Taylor
diagrams.
