    Accelerating CO<sub>2</sub> Outgassing in the Equatorial Pacific from Satellite Remote Sensing by Yiwu Shang, Jingyuan Xi, Yi Yu, Wentao Ma, Shuangling Chen

    Published 2025-01-01
    “…In this study, we addressed this challenge using monthly surface partial pressure of CO<sub>2</sub> (<i>p</i>CO<sub>2</sub>sw) and air-sea CO<sub>2</sub> fluxes (FCO<sub>2</sub>) data products reconstructed from satellite and reanalysis data at a spatial resolution of 1° × 1° in the period of 1982–2021. We found that during the very strong El Niño events (1997/1998, 2015/2016), both <i>p</i>CO<sub>2</sub>sw and FCO<sub>2</sub> showed a significant decrease of 41–58 μatm and 0.5–0.8 mol·m<sup>−2</sup>·yr<sup>−1</sup> in the eastern equatorial Pacific, yet they remained at normal levels in the western equatorial Pacific. …”
