To date, significant uncertainties exist in our understanding of the global and regional cycles of CO2 and CH4. Remote sensing technologies for measuring CO2 and CH4 from space, from the ground, from aircraft
and other platforms have been significantly further developed over the last years. This covers aspects such as instrument development and calibration, retrieval techniques, validation, modelling
and interpretation in terms of surface fluxes.
In 2009 the satellite instrument GOSAT has been launched, which is supposed to significantly improve our ability to monitor the greenhouse gases CO2 and CH4. Significant advances have been made also in many other areas related to passive and active remote sensing of CO2 and CH4.
This session is open to contributions related to all aspects of remote sensing of the greenhouse gases CO2 and CH4 from current (e.g., SCIAMACHY, AIRS, IASI, GOSAT), upcoming and planned satellite missions, as well as ground-based (e.g., TCCON), aircraft
and other remote sensing observations including instrument development, calibration, retrieval techniques, analysis of retrieved data products, validation, modelling and interpretation in
terms of surface fluxes.
