Short summary
Relative contribution from precipitation and temperature to interannual variability (IAV) of atmospheric CO2 growth rate (CGR) remains uncertain. We found that CGR IAV has a slightly higher correlation coefficient with temperature than precipitation. However, Trendy models can well simulate the IAV and consistently show net primary production dominates it. These mechanistic analyses suggest a key role of precipitation in CGR IAV despite the higher CGR correlation with temperature.
