As part of its user engagement activities, the CoCO2 project has now published a new web-based interface to a collection of published studies on satellite identification of hot-spot emissions. The tool provides an online repository of studies in the peer-reviewed literature about the use of satellite data to detect and estimate hot-spot emission of carbon dioxide (CO2) and methane (CH4). Its purpose is to inform users with different backgrounds about current state-of-the-art information on research being already done in the field of the detection and quantification of hot-spots emissions by satellites, in preparation for the next Copernicus CO2M satellite constellation.
