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
Nitrous-oxide reductase competent unit. The Cu center can undergo a one-electron redox change and hence has a function similar to that in the well-known aa-type cytochrome "c" oxidases () where it serves to receive an electron from soluble cytochromes "c". Acetylene is the most specific inhibitor of nitrous-oxide reductase. Other inhibitors include azide anion, thiocyanate, carbon monoxide, iodide, and cyanide. Nitrous-oxide reductase In enzymology, a nitrous oxide reductase also known as nitrogen:acceptor oxidoreductase (NO-forming) is an enzyme that catalyzes the final step in bacterial denitrification, the reduction of nitrous oxide to dinitrogen. It plays a critical role in preventing release of a
