Total Carbon Column Observing Network these include The satellite missions supported by the TCCON include the Greenhouse Gases Observing Satellite (GOSAT), SCIAMACHY, and the Orbiting Carbon Observatory-2 (OCO-2). Total Carbon Column Observing Network The Total Carbon Column Observing Network (TCCON) is a global network of instruments that measure the amount of carbon dioxide, methane, carbon monoxide, nitrous oxide and other trace gases in the Earth's atmosphere. The TCCON ( ) began in 2004 with the installation of the first instrument in Park Falls, Wisconsin, USA, and has since grown to 23 operational instruments worldwide, with 7 former sites. The TCCON is designed to investigate several
Carbon dioxide of hydrogen by steam reforming and the water gas shift reaction in ammonia production. These processes begin with the reaction of water and natural gas (mainly methane). This is a major source of food-grade carbon dioxide for use in carbonation of beer and soft drinks, and is also used for stunning animals such as poultry. In the summer of 2018 a shortage of carbon dioxide for these purposes arose in Europe due to the temporary shut-down of several ammonia plants for maintenance. Acids liberate from most metal carbonates. Consequently, it may be obtained directly from natural carbon dioxide springs, where
