Remote Sensing of CH4 and CO2 from Space: The Expanding Observing System

Session ID#: 119869

Session Description:
This session explores the impact of remote sensing observations of atmospheric methane, carbon dioxide, and related quantities on the understanding of processes driving variability in sources and sinks at local to global scales. The TROPOMI instrument launched in late 2017, and has been collecting dense measurements of CH4, CO, and solar induced chlorophyll fluorescence with nearly global coverage each day. Adding to the CO2 record, GOSAT-2 was launch in late 2018, and OCO-3 and PRISMA in early 2019. These missions complement existing greenhouse-gas satellites including GOSAT, OCO-2, and GHGSat. With these space-based sensors joined by an expanding range of in-situ and ground-based observational efforts, we are entering an age of great opportunity for fundamental breakthroughs. We call for submissions of analysis of existing datasets, outlining innovative measurement approaches, advances in retrieval algorithms, development of gridded fields, and data analysis / modeling tools that target forthcoming and existing observations.
