2nd User Workshop

To explore the satellite-derived ozone Climate Data Records developed by the ESA Climate Change Initiative


The European Space Agency’s Climate Change Initiative (CCI) aims to realise the full potential of the long-term Earth Observation archives collected by ESA and Third Party satellite missions. Since 2010, the Ozone CCI team has been developing, maturing, generating and sustaining multiple complementary multi-decadal satellite ozone Climate Data Records (CDRs) tailored for climate monitoring, climate research and climate modelling applications. The CCI portfolio consists of total and tropospheric ozone column data products as well as vertically resolved ozone products by nadir and limb-viewing sensors.

Workshop objectives

This second user workshop will be an online event (28-29 May 2024) is aimed at bringing together scientists involved in the generation of ozone Climate Data Records, as well as (potential) users of such multi-decadal ozone time series, and the broader ozone and climate communities:

  • presenting the state of the art in ozone Climate Data Record production;
  • discussing results from major Climate Data Record users, e.g., stratospheric ozone assessments for WMO/UNEP, tropospheric ozone assessments for TOAR II, studies focusing on UT/LS, evaluation of climate modelling, data assimilation and reanalysis;
  • collecting and updating user requirements for ozone Climate Data Records;
  • discussing remaining challenges for the generation of ozone Climate Data Records.

Organising committee

  • Dr. Martin Dameris (DLR, Germany)
  • Dr. Michiel van Weele (KNMI, The Netherlands)
  • Dr. D. Hubert (BIRA-IASB, Belgium)
  • Mrs. N. Kalb (BIRA-IASB, Belgium)
  • Mr. Michael Eisinger (ESA ECSAT, UK)

Call for abstracts

We welcome contributions from the Earth Observation, climate monitoring and climate modelling communities, specifically related to

  • recent developments and emerging challenges in the generation of long-term ozone Climate Data Records from satellite or ground-based sensors;
  • assessments of long-term ozone changes and variability in troposphere, stratosphere and UT/LS;
  • the evaluation of climate models, data assimilation and reanalyses using satellite Climate Data Records;
  • the combined use of ozone and other Essential Climate Variables (atmosphere, oceans, biosphere, cryosphere) to improve our understanding of the Earth system.

You are required to register to the workshop in order to submit an abstract. After submission you can modify/withdraw your abstract until the deadline.

All times displayed are automatically adjusted to the timezone set by the page visitor (top right of this window).
