To ascertain the global and geophysical flux values of CO_2 and their seasonal and inter-annual variation, detailed CO_2 measurements including vertical distribution are required. Vertical CO_2 distribution in the troposphere, particularly in the planetary boundary layer, is key to estimate the local surface flux of CO_2. However, measurements of the vertical distribution are limited to some specific regions where specially equipped aircrafts are available. We are developing a low-cost, easy-to-operate, all-weather CO_2 sonde flown with a meteorological balloon. Balloon experiments with the CO_2 instruments were performed more than 10 times. The vertical profiles of CO_2 Mixing ratio were obtained with the vertical resolution of 300 m and precision of 1 ppm.

为了确定全球和地球物理CO_2通量值及其季节和年际变化，需要详细的CO_2测量，包括垂直分布。对流层中CO_2的垂直分布，特别是行星边界层中的CO_2垂直分布，是估算局地CO_2通量的关键。然而，对其垂直分布的测量仅限于一些有特殊装备的飞机可用的特定地区。我们正在开发一种低成本、易操作、全天候的CO_2探测仪，它与气象气球一起飞行。用CO_2装置进行了10次以上的气球实验。得到了垂直分辨率为300m、精度为1ppm的CO_2混合比垂直剖面。
