Observation data show large interannual variability of atmospheric CO2.By analyzing yearly mean observation data of global precipitation and atmospheric CO2mixing ratio at Mauna Loa Observatory, we have found a significant positive correlation between the interannual variability of CO2growth rate and the year-to-year changes in global land precipitation.We suggest that this positive correlation results mainly from the influence of clouds in Monsoon areas on terrestrial net ecosystem production (NEP).Here a set of monthly mean data of temperature, precipitation and atmospheric CO2 is used to reanalyze their relationships.In addition, we use satellite-based monthly grid cloud data over the period of 1984～ 1993 to study its relationship with atmospheric CO2 and find that the interannual variability of atmospheric CO2matches cloud cover growth rate.
