The French Space Agency (CNES) is working on MicroCarb, a micro satellite that will measure gas concentrations in the entire atmospheric column above every country around the globe with a precision of 1 ppm.
The satellite will carry a 4-wavelength passiveinfrared spectrometer. It will measure the spectral radiance of the solar radiation reflected by the planet to detect CO2 particles, as well as methane and other gases. Big as a microwave, MicroCarb will consume no more power than a 60-watt light bulb and cover the entire Earth in two weeks. Launch is planned for 2020.
At this month’s COP 21 in Paris, many participants identified the need for a global surveillance satellite network able to locate and quantify CO2 emissions. Two satellites already have been launched—the Japanese Gosat in 2009, followed by the American OCO-2 in 2014. Industry is on notice. Satellites will soon measure CO2 emissions in every region of the globe.
