            【摘要】:The variation of the atmospheric Carbon Dioxide(CO_2) concentration plays an important role in global climate and agriculture.We analyzed the spatial-temporal characteristics of CO_2 in the China region and around the globe with the CO_2 column mixing ratios observed by the Japanese GOSAT satellite(Greenhouse Gases Observing Satellite).In order to make sure that the accuracy of the CO_2 data retrieved by the satellite meets the needs of the climate characteristics analyses,we ran a validation on the CO_2 column mixing ratios retrieved by the satellite against the ground-based TCCON(Total Carbon Column Observing Network) observation data.The result shows that the two sets of data have a correlation coefficient of higher than 0.7,and a bias of within 2.2 ppmv.Therefore,the GOSAT CO_2 data can be used for the climate characteristics analysis of global CO_2.Our analysis on the spatial-temporal characteristics of the CO_2 column mixing ratios observed during the period of June 2009 through January 2014 proved that,with the impact of the natural emission of near ground CO_2 and human activities,the global CO_2 concentration has a significant latitudinal characteristics with its highest level averaging 390 ppmv in the 0-40?N latitudinal zone in the Northern Hemisphere,and 387 ppmv in the Southern Hemisphere.China has a relatively higher CO_2 concentration with the highest level exceeding 398 ppmv,and the eastern area higher than the western area.The variation of global CO_2 concentration shows a seasonal pattern,i.e.the CO_2 concentration reaches its highest in spring in the Northern Hemisphere averaging more than 392 ppmv,second highest in winter,and lowest in summer averaging less than 387 ppmv.It fluctuates the most in the Northern Hemisphere with an average concentration of 392.5 ppmv in April,and 385.5 ppmv in July.While in the Southern Hemisphere,the seasonal fluctuation is smaller with the highest concentration occurring in July.Over the recent years,the global CO_2 concentration has shown an elevating trend with an average annual increase rate of 1.58 ppmv per year.It is a challenge that the human kind has to face to slow down the increase of the CO_2 concentration.
