Estimates of Total (σ T), Forced (σ F), and Chaotic Intrinsic Variability (σ I) of Sea‐Air CO2 Fluxes Integrated Over the Global Ocean and Over Three Regions With High Eddy Kinetic Energy
| Sea‐air CO2 flux (TgC yr−1) | σ T (TgC yr−1) | σ F (TgC yr−1) | σ I (TgC yr−1) | σ I 2/σ T 2 (%) | Error e (TgC yr−1) |
|---|---|---|---|---|---|
| Global ocean 78°S to 90°N | 673.5 | 652.1 | 158.0 | 5.5 | 86.3 |
| Midlatitude Southern Ocean 45–35°S | 52.7 | 47.4 | 23.8 | 20 | 13.0 |
| Gulf Stream 70°W, 40°W to 35°N, 50°N | 9.91 | 9.16 | 3.99 | 16 | 2.18 |
| Kuroshio 140°E, 170°E to 30°N, 45°N | 10.5 | 9.46 | 4.92 | 22 | 2.68 |
Note. The ratio of variances (σ I 2/σ T 2) provides a measure of the contribution of CIV to the total variability. The error (e) has been estimated at each grid point of the global ocean following Equation 2 and integrated over the area of interest.
