National Methane Days 2022

September 21 @ 13 h 00 min - September 22 @ 17 h 00 min

Methane is the second anthropogenic greenhouse gas after CO2. Its emissions are estimated at 580 Mt/year[1] and contribute[2] to global warming to the tune of 2/3 of the effect of CO2 emissions. This importance is linked to the fact that the warming power of methane is about 30 times greater than that of CO2 over a 100-year period. Its lifetime of about ten years, which brings the effects of a reduction in emissions within human reach, and its indirect impact on air pollution, as a precursor of ozone, make it a prime target for mitigating global warming and improving air quality, as was well highlighted in the latest IPCC Group 1 report (IPCC, 2022). One complexity of methane is the variety of its sources and sinks, the study of which mobilises many skills and therefore also many scientific, experimental and modelling communities. The scientific questions cover the study of wetlands and continental waters, oceanic and continental outgassing, the estimation of anthropogenic emissions at all scales in the various sectors of activity, atmospheric spectroscopy, atmospheric chemistry, the development of methane observation from space, etc. This variety is a richness but also a difficulty because the different communities are rarely brought together to offer an overall vision, which is nevertheless essential, of the methane cycle. The French scientific communities are present on many fronts of methane studies, as was the case during the first methane day in 2015, seven years ago. In this context, it is proposed to organise a new edition of the National Methane Days in order to bring together the French scientific communities working on methane, as well as interested industrial partners, to exchange and take stock of recently acquired knowledge and future challenges. This “day” will take place from 21 September at 1pm to 22 September 2022 at 2pm, in Paris, in the CNES space room. Organising committee : Carole Deniel (CNES) Cyril Crevoisier (CNRS/LMD) Marielle Saunois (UVSQ/LSCE) Jean-Daniel Paris (CEA/LSCE) Fabrice Jegou (CNRS/LPC2E) Frédéric Guérin (IRD/GET) Philippe Bousquet (UVSQ/LSCE) Kathy Law (CNRS/LATMOS) Patricia Martinerie (CNRS/IGE) Lilian Joly (Univ. Reims) The day will be organised around oral presentations, posters, and moments of collective exchange and debate. Coffee breaks will be provided, and a buffet will be offered on 22 September 2022 at the end of the debates. A call for papers is attached to this letter. Entry will be free of charge but registration is compulsory. Coffee breaks and the buffet on 22 September are free of charge. The meal on the evening of 21 September is not covered. Registration and submission of abstracts: to come Deadline for submission of abstracts: 15 June 2022.
