1. 1 Influence of El Niño on AIRS CO 2 08/06/2008

2. 2 Low CO2 flux during the 1992-94 ENSO event compared with 1996 non-El Nino year in the central and eastern Pacific. [Feely et al., 1999]

3. 3 Less upwelling of CO2-enriched water from the equatorial undercurrent leads to less CO2 released to atmosphere.
