Chemical composition and climate

Changes in the Earth system induced by human activities and their impact on life and natural environment are arguably the greatest environmental challenge facing us in the twenty- first century.

In order to inform decision makers on climate change mitigation and adaptation, a systematic monitoring of the global atmosphere and climate system is needed.

BIRA-IASB is involved in several important international programmes and projects, such as:

  • ESA Climate Change Initiative (CCI)
  • Copernicus Atmosphere Monitoring (CAMS)
  • Climate Change Service (C3S)
We are proud to present a new introductory film, in which the Royal Belgian Institute is being presented in all its facets. Discover the many fields of research and societal challenges in which the Institute is active.
The hole in the ozone layer above the Antarctic is very deep this year, due to the exceptionally cold temperatures in the stratosphere.
Scientists from the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) used satellite data from TROPOMI to explore the links between COVID-19 and the effects of nitrogen dioxide levels (NO2) since the beginning of the crisis until today.
BIRA-IASB published an article in Nature Geoscience, presenting the first unambiguous detection of nitrous acid (HONO) from space, revealing the existence of enhanced HONO over wildfires.
An ICOS synthesis study describing the fingerprint of the 2018 summer drought in Europe trough measurements of CO2.
The launch of Vega Flight VV16, which will put the Belgian CubeSats PICASSO and SIMBA into orbit, has been postponed to August.
Is the sky clearer and bluer since the start of the lockdown? Where does the colour of the sky comes from?
Space-borne and ground-based instruments can detect such fires from space, as part of the Copernicus Earth Observation programme coordinated by the European Commission.
ICOS (Integrated Carbon Observation System) label for the Maïdo station on Reunion Island for BIRA-IASB.
Dormant since 1924, the Raikoke Volcano in the Kuril Island chain, near the Kamchatka Peninsula in Russia, recently awoke. Copernicus Sentinel-5P and Sentinel-3 satellites are giving vital information.
We contribute to the reflections on how we can adapt our lifestyle and our way of working to contribute to a climate-neutral society.
