SHIVA - Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere


Belgian Institute for Space Aeronomy, Belgium (BIRA-IASB)


The Belgian Institute for Space Aeronomy is a research institute of the Belgian federal government. One of its main foci concerns research investigations in the field of atmospheric physics and chemistry. Since its creation in 1964, it has developed a strong expertise in remote sensing techniques using optical spectroscopy, in particular in the field of ground-based and space-based UV-Visible and FTIR atmospheric trace gas monitoring. It also has an internationally recognized expertise in tropospheric and stratospheric modelling, including inverse source modelling and 4D-var data assimilation. Since the launch of the GOME instrument on ERS-2 in 1995, BIRA-IASB has been deeply involved in the development of scientific trace gas retrieval algorithms applied to nadir backscattered observations, in particular focusing on the global monitoring of BrO, ODSHO, NO2 and SO2. It also has a strong involvement in the activities of the NDACC network, operating ground-based instruments for regular monitoring stratospheric using DOAS instruments, and leading its UV-Vis working group. Within the SHIVA project, BIRA-IASB will contribute to WP-2 with BrO and IO retrievals from GOME-2, and to WP-5 with an analysis of the long-term evolution of the stratospheric bromine loading using NDACC ground-based observations.

Tasks within SHIVA:

  • BrO and IO retrievals from GOME-2 with emphasis on the abundance of these trace gas species in the troposphere (WP-2).
  • Study of the trends in the stratospheric bromine loading using existing NDACC ground-based observations (WP-5).
