Targeted specialised climate research community

Users of chemistry-climate models (CCMs) with particular focus on long-term numerical simulations using CCMs for the detailed investigation of model feedbacks between ozone chemistry, ozone depleting substance (ODS) trends, and climate.

The figure below gives a nice example for an oriented comparison of observations and CCM results. It is based on climatological mean values which needs long-term, consolidated data series. The data basis of observations are total ozone columns measurements from three satellite borne instruments: the European satellite sensors GOME (ERS-2), SCIAMACHY (ENVISAT), and GOME-2 (METOP-A) are combined and added up to a continuous time series starting in June 1995. The simulations are from the CCM E39C-A model (Loyola et al., 2009).

This community is involved in

international activities of climate research including stratospheric and tropospheric responses and feedbacks.

Ozone_cci has its own Climate Research Group

in order to assure a real link with these user groups. They will gather the requirements from the wider climate research community from an end user and modeler perspective in order to ensure that the ESA CCI meets the Global Climate Observation System (GCOS) and Climate Research Community (CRC) requirements.

Who are the members of our Climate Research Group?

  • DLR-PA (Martin Dameris)
  • KIT (Peter Braesicke)
  • KNMI (Peter van Velthoven, Michiel van Weele)

These groups are already actively participating in international activities of climate research (IPCC) including stratospheric responses and feedbacks (WMO).

The CCM validation activity for SPARC (CCMVal) is another example for an internationally organised and coordinated activity of the chemistry-climate community. CCMVal is an important corner stone for the interpretation of recent climate and ozone changes and the assessment of possible future development. The PIs of DLR-PA, KIT and KNMI were and currently are lead- and (co-)authors of the respective scientific documents (IPCC, WMO).

A User Requirements Document has been issued to identify the needs of the climate research community.
