Stratospheric composition and climate | 2021-2022

Assessment of changes in the Brewer-Dobson circulation in the past decade using satellite and ground-based observations and model simulations of the long-lived tracer nitrous oxide.

Integration of the stratospheric chemistry module BASCOE into the European atmospheric model IFS, as well as the extension of the aerosol module in the IFS from the troposphere to the stratosphere.

Three-decade expertise in satellite validation to develop operational services ensuring the necessary quality assessment of atmospheric data, interoperability of different sounders, and early warning of anomalies.

Satellite observations help us to identify aerosols and understand their role. BIRA-IASB provides aerosol climate data records to the scientific community.
