Terrestrial mechanisms of interannual CO 2 variability

  title={Terrestrial mechanisms of interannual CO 2 variability},
  author={Ning Zeng and Annarita Mariotti},
[1] The interannual variability of atmospheric CO2 growth rate shows remarkable correlation with the El Niño Southern Oscillation (ENSO). Here we present results from mechanistically based terrestrial carbon cycle model VEgetation-Global-Atmosphere-Soil (VEGAS), forced by observed climate fields such as precipitation and temperature. Land is found to explain most of the interannual CO2 variability with a magnitude of about 5 PgC yr . The simulated land-atmosphere flux has a detrended… CONTINUE READING
