Two EGU26 sessions on atmospheric composition, including greenhouse gases that may be of interest to the IG3IS community:

Session AS3.26 (PICO): Atmospheric composition variability and trends. See details here.

Session AS3.38: "Science-based, measurement-based greenhouse gas emission monitoring to inform climate change mitigation across decision-making scales and sectors."  See details here.
