COCCON Version 5 dataset from the atmospheric observatory of Karlsruhe (Germany) available at the EVDC Data Handling Facilities covering start date Mar 27 2014 to end date Dec 2 2025

COCCON uses the EM27/SUN spectrometer commercially available from Bruker Company. The spectrometer performs solar absorption measurements in the NIR for the measurement of column-averaged abundances of atmospheric greenhouse gases (CO2, CH4, CO, and H2O). COCCON requires the use of calibrated spectrometers and of common data analyses tools (see http://www.coccon.kit.edu).

COCCON采用布鲁克（Bruker）公司商用发售的EM27/SUN型光谱仪。该光谱仪可在近红外（NIR）波段开展太阳吸收测量，以测定大气温室气体（CO₂、CH₄、CO及H₂O）的柱平均丰度。COCCON需使用经过校准的光谱仪与通用数据分析工具，详细信息请参见http://www.coccon.kit.edu。
