Methane plume from landfill

Methane plume measured during the Comex campaign to support the development of CarbonSat – one of the two candidates for ESA’s eighth Earth Explorer satellite mission. The campaign was carried out in August–September 2014 in California, USA. In a joint effort, the campaign also supported the development of NASA’s Hyspiri satellite. The measurements collected by Mamap on an aircraft clearly show that a landfill site near Los Angeles is emitting methane (shown in red) and that it is travelling in the same direction as the wind.
