First Announcement: Ozone_CCI User Workshop in May 2024

28-29 May 2024, two half-day virtual sessions (virtual meeting)

Background: 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 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.

Objectives: The main objectives of this workshop are (a) to bring together scientists involved in the generation of ozone CDRs, as well as (potential) users of ozone CDRs, and the broader ozone and climate communities, (b) to present the state of the art in ozone CDR production, (c) to discuss results from major CDR users (e.g., stratospheric and tropospheric ozone assessments, UT/LS studies, evaluation of climate modelling, data assimilation and reanalysis), (d) to collect and update user requirements for CDRs, and (e) to discuss remaining challenges for the generation of ozone CDRs.

Organising team: M. Dameris, D. Hubert, M. van Weele, N. Kalb, C. Retscher Further information can be found at
