Chemical composition and climate | 2019-2020

VOC measurements in La Réunion to search for clues on missing sources of VOCs in biomass burning plumes from Africa.
Satellite observations might help to answer that question and better account for human-driven land use practices (forest to crop or pasture conversion, logging and urbanization).
Improving our understanding of methane (CH4), an important greenhouse gas, from space, using ground-based instruments and performing satellite quality control studies.
To study the impact of global atmospheric currents in the stratosphere and mesosphere on the ozone layer and on nitrous oxide (N2O) we compared datasets.
Monitoring tropospheric ozone is key to verifying whether scientific understanding and regulations are sufficient to protect public health and ecosystems.
A homogenized formaldehyde (HCHO) data set from FTIR measurements has been developed including more than 25 stations over the world.
European research infrastructures ensure long-term state-of the-art measurements of atmospheric constituents from ground-based instruments.
BIRA-IASB implemented the WRF-GHG model to simulate the transport and surface fluxes of CO2, CH4 and CO with a spatial resolution up to 1 km2.
BIRA-IASB provides atmospheric data to the European Copernicus programme for various atmospheric species, including stratospheric aerosols.
Understanding aerosols, and in particular the particle size, is a major issue for the study and modelling of climate change.
