Significant uncertainties remain in our understanding of Carbon Dioxide (CO2) and Methane (CH4) fluxes across land, ocean, and atmosphere at both regional and global scales. Remote sensing of CO2 and CH4 offers great potential to enhance our understanding of the natural carbon cycle and to monitor anthropogenic emissions. Recent advances in CO2 and CH4 remote sensing technologies, spanning spaceborne, airborne, and ground-based platforms, have delivered unprecedented accuracy and coverage. Furthermore, next-generation platforms such as CO2M, Merlin, TANGO, and CO2Image promise to further enhance observational capabilities. When integrated with ground-based observation networks and modeling tools, these space-based observations can significantly improve our understanding of the carbon cycle from local to global scales.
This session invites contributions on all aspects of CO2 and CH4 remote sensing, including current missions (e.g., GOSAT/2/GW, OCO-2/3, S5P/S5, IASI-NG, Carbon Mapper, MicroCarb, GHGSat), upcoming and planned missions (e.g., CO2M, Merlin, TANGO), as well as ground-based networks (e.g., TCCON and COCCON), airborne platforms, and other remote sensing instruments. We welcome contributions on advances in retrieval techniques, instrument concepts, and validation activities, with an emphasis on interpreting observations related to natural fluxes and anthropogenic emissions.
