Space-based X <strong>CO</strong>2 measurements<br />
with precisions of 1–2 ppm (0.3–<br />
0.5%) on regional scales will:<br />
• Resolve pole to pole X <strong>CO</strong>2<br />
gradients on regional scales<br />
• Resolve the X <strong>CO</strong>2 seasonal cycle<br />
in the Northern Hemisphere<br />
• Improve constraints on <strong>CO</strong> 2 fluxes<br />
(sources and sinks) compared to<br />
the current knowledge<br />
– Reduce regional scale flux<br />
uncertainties from >2000 gC m -2<br />
yr -1 to < 200 gC m -2 yr -1<br />
– Reduce continental scale flux<br />
uncertainties below 30 gC m -2 yr -<br />
