英文摘要	From TOPEX/Poseidon data, the significant uncertainty in global air-sea carbon dioxide (CO2) flux in 2000 is calculated from 21 wind-speed-dependent and 5 sea-state-dependent CO2 transfer velocities and the sea-to-air partial pressure difference Delta p(CO2) proposed by Takahashi, Sutherland, and Kozyr (2010). The sea-state-dependent parameterizations are calculated based on the significant wave height (SWH) and the radar backscatter coefficient sigma(0) measured using the Ku-band altimeter. Uncertainty in air. sea CO2 flux is compared using 26 various transfer velocity formulas. The maximum differences in global monthly mean and 4 degrees zonal mean values for gas transfer velocity among these formulas are 33.20 and 108.20 cm hour (1), respectively. The corresponding differences for sea-to-air CO2 flux are 6.41 and 0.58 Pg C year (1), respectively. Monthly mean global maps of gas transfer velocity and flux are also presented. The average value of the global mean, transfer velocity obtained using the 26 formula is 27.33 +/- 9.75 cm hour (1), and the averaged total global net air-to-sea CO2 flux is 2.77 +/- 1.02 Pg C year (1) after area weighting and Schmidt number correction. The sea-state-dependent parameterizations are near these values, providing a successful method to estimate the air. sea CO2 transfer velocity and flux.
