摘要：

We compare here the air-sea exchange coefficient for CO2 estimated with monthly mean wind speed measured by the Special Sensing Microwave Imager (SSM/I), K-S, and by the scatterometer QuikSCAT, K-Q, for the year 2000. K-S and K-Q present the same patterns, although are larger than in similar to65% of the world ocean. Zonal mean K-S are consistently larger, except similar to50degreesS and north of 10degreesS in the Indian Ocean. Global oceanic uptake, F-Q, estimated using K-Q and climatological Deltap(CO2) ranges from 0.43 (July) to 2.6 Gt C y(-1) (December). The global sink estimated from SSM/I is similar to10% larger than F-Q for most of the year. This comparison supports the use of SSM/I to quantify interannual variability of the global exchange coefficient of CO2.
