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 fuel blend Nitrous oxide fuel blend Nitrous Oxide Fuel Blend propellants are a class of liquid rocket propellants intended to replace hydrazine as the standard rocket fuel. The fuel and oxidizer are blended and stored; this is sometimes referred to as a "mixed monopropellant". Upon use, the propellant is heated or passed over a catalyst bed and the nitrous oxide decomposes into oxygen-rich gasses. Combustion then ensues. Special care is needed in the chemical formulation and engine design to prevent detonating the stored fuel. The agent used for rocket fuel in a shuttle is paramount; weight, thrust, cost, toxicity, risk of explosions
