[Im4ca.all.beta] EGU-2026 Call for abstracts, session AS3.24 "Remote Sensing of Carbon Dioxide and Methane from Space"

[Houweling, S. (Sander)]

Dear colleagues in the GHG remote sensing community,

Happy new year! I’d like to inform you about our recurring EGU session on "Remote Sensing of Carbon Dioxide and Methane from Space" that will be organized again this year at EGU-2026, 3-8 May in Vienna and online.
If you would like to contribute then please be reminded that the abstract submission closes on 15 January, 13:00 CET.

The aim and scope of the session are as follows:
Significant uncertainties remain in our understanding of Carbon Dioxide (CO2) and Methane (CH4) fluxes across land, ocean, and atmosphere on both regional and global scales. Remotely sensed CO2 and CH4 observations hold great potential for enhancing our understanding of the natural carbon cycle and monitoring anthropogenic emissions. Recent advances in remote sensing technologies for CO2 and CH4, spanning space, aircraft, and ground-based platforms, have delivered unprecedented accuracy and coverage. Moreover, upcoming next-generation platforms like CO2M, MicroCarb, GOSAT-GW, and MethaneSAT 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 at both local and global scales.

This session invites contributions on all aspects of remote sensing of CO2 and CH4, covering current missions (e.g., GOSAT/2, OCO-2/3, S5P, EMIT, Carbon Mapper, GHGSat, EMIT), upcoming and planned missions (e.g., CO2M, MicroCarb, Merlin, GOSAT-GW, MethaneSAT), as well as ground-based (e.g., TCCON, COCCON), aircraft, and other remote sensing instruments. We welcome advances in retrieval techniques, instrumental concepts, and validation activities, with a particular emphasis on interpreting observations related to natural fluxes or anthropogenic emissions.

Please forward this announcement to anyone not addressed in the recipient list.

We are looking forward to meeting you in Vienna!
Sander Houweling (on behalf of co-conveners Dietrich Feist, Matthaeus Kiel, Max Reuter, and Neil Humpage)
