Figure 8 A global map of the annual gas exchange coefficient for carbon dioxide for the year 2001. The map was derived from a combination of wind speeds derived from the QSCAT satellite sensor and the W92 parametrization of Note that has been corrected for the solubility of CO2 in this figure (reproduced by permission of Dr. J.

Finally, a note on the calibration of sensors for carbon dioxide. This is traditionally achieved using commercially available gas mixtures or producing mixtures using flow meters. In some laboratories sensors may be calibrated against a mass spectrometer although the expense of such Instruments limits their use considerably. In a recent communication Calabrese and Maillet describe a photochemical method of producing reproducible...
