To date, significant uncertainties exist in our understanding of the global and regional cycles of CO2 and CH4. Remotely-sensed CO2 and CH4 observations provide a significant potential for improving our understanding of the natural carbon cycle and for the monitoring of anthropogenic emissions.

Over the last few years, significant advances have been made in remote sensing technologies for measuring CO2 and CH4 from space, from the ground or from aircraft and observations from numerous passive and active instruments from different platform are available now.

This session is open to contributions related to all aspects of remote sensing of the greenhouse gases CO2 and CH4 from current, upcoming and planned satellite missions, as well as ground-based (e.g., TCCON), aircraft, other remote sensing observations, including the use of modeling techniques.

We specifically encourage contribution that focus on the interpretation of observations from existing sensors and on the development of future sensors and technologies for greenhouse gas remote sensing.
