Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 3987-3998 (2020)

Characterizing methane sources in the Arctic remains challenging due to the remoteness, heterogeneity and variety of such emissions. In situ campaigns provide valuable datasets to reduce these uncertainties. Here we analyse data from the summer 2014

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 12141-12161 (2019)

Recent efforts have brought together bottom-up quantification approaches (inventories and process-based models) and top-down approaches using regional observations of methane atmospheric concentrations through inverse modelling to better estimate the

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Pp 8371-8394 (2017)

Understanding the recent evolution of methane emissions in the Arctic is necessary to interpret the global methane cycle. Emissions are affected by significant uncertainties and are sensitive to climate change, leading to potential feedbacks. A po

Signature of tropical fires in the diurnal cycle of tropospheric CO as seen from Metop-A/IASI

Autor: T. Thonat, C. Crevoisier, N. A. Scott, A. Chédin, R. Armante, L. Crépeau

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 22, Pp 13041-13057 (2015)

Five years (July 2007 to June 2012) of CO tropospheric columns derived from the hyperspectral Infrared Atmospheric Sounding Interferometer (IASI) on-board Metop-A are used to study the impact of fires on the concentrations of CO in the troposphere. F

Publikováno v: Atmospheric Measurement Techniques, Vol 5, Iss 10, Pp 2413-2429 (2012)

Four years of tropospheric integrated content of CO were retrieved from infrared hyperspectral observations of AIRS onboard Aqua and IASI onboard MetOp-A, for the period July 2007–June 2011. The retrieval method is based on a double differential ap
