Stratospheric ozone monitoring

BIRA-IASB studies the Earth’s stratosphere by looking at long-term changes in stratospheric ozone and the evolution of greenhouse gases.

These important constituents will be measured by the ALTIUS satellite mission, an innovative design created by BIRA-IASB scientists.

BIRA-IASB also focuses on related key parameters like:

  • volcanic aerosols
  • polar stratospheric clouds
  • halogenated compounds

The development of the BASCOE model and data assimilation system has brought to BIRA-IASB a strong competence in the modeling of chemical composition in the stratosphere and its quantitative comparison with satellite and ground-based observations.

The largest hole in the ozone layer ever recorded over the North Pole. Unusual meteorological conditions are responsible.
