为了了解中国大陆大气温室气体的变化，于2003年3月建立了包括1个全球大气观测站、3个全球大气观测区域站和3个合作站的大气采样网络。连续3年每周在各监测站采集烧瓶空气样本。在所有观测站都可以清楚地观察到CO2浓度的长期增加和季节变化，反映了全球和区域陆地生物圈和人类活动以及当地的气象条件。平均CO2浓度取决于站点，最低值在Mt.分别在中国最西部和东部的阜康站和临安站观测到的瓦里关和相对较高的值。观测到的CO2浓度变化也讨论了使用随时间变化的反演得到的CO2通量的前向传输模型模拟的背景下。
In order to understand the variations of atmospheric greenhouse gases over the Chinese mainland, an air sampling network was established in March 2003 that included one GAW global station, three GAW regional stations and three cooperative stations. Flask air samples were taken every week at the stations for 3 years. The secular increase and the seasonal variation in the CO2 concentration are clearly observable at all the stations, reflecting global as well as the regional terrestrial biospheric and human activities, as well as the local meteorological conditions. The average CO2 concentration depends on the station, with the lowest value observed at Mt. Waliguan and relatively high values observed at Fukang and Lin‐an stations, located in the westernmost and eastern parts of China, respectively. The observed CO2 concentration variations are also discussed within the context of forward transport model simulations using CO2 fluxes derived by time‐dependent inversion.
