The impact of interannual
variability on air-sea CO2 fluxes and oceanic dissolved inorganic
carbon fields: numerical experiments in the NCAR CSM Ocean Model (NCOM)
NOAA/DOE OACES, 36 months |

PROJECT DESCRIPTION: | The preliminary analysis of the WOCE/JGOFS global
ocean carbon survey has contributed greatly to an improved understanding
of the mean and perturbed state of the ocean carbon cycle. The global
carbon data set and associated new data analysis techniques have helped
to clarify among other issues the air-sea CO2 flux fields, the
natural dissolved inorganic carbon background distributions, and the long-term
uptake patterns of anthropogenic carbon. A decade long, one-time
global survey, however, is less useful for constraining the temporal variability
of the ocean, for which we will have to turn to more directed measurement
programs and numerical models. Here, I propose to evaluate the impact
of interannual climate variability on the ocean carbon system using a state
of the art numerical global ocean circulation model, the NCAR CSM Ocean
Model (NCOM), driven with synoptic atmospheric forcing data sets either
from the NCEP reanalysis (1957-1996) or the coupled NCAR Climate System
Model.
The analysis of the resulting model variability in the air-sea CO2 flux and subsurface dissolved inorganic carbon distribution will be focused on two related questions:
